Method for manufacturing disposable endoscopic puncture outfit for laparoscopy operations and a puncture outfit using the method

Abstract

A method for manufacturing a disposable endoscopic puncture outfit for laparoscopy operations and a puncture outfit made according to the method are provided. The puncture outfit has a camera shooting module with a light source, a puncture needle and a positioning puncture casing pipe that matches with the puncture needle; the camera shooting module is set at a head end of the puncture needle; the head end of the puncture needle is sheathed with a transparent cover that can cover the camera shooting module; the puncture needle is inserted in the positioning puncture casing pipe to make the transparent cover at the head end of the puncture needle slightly extend out of the positioning puncture casing pipe. The puncture outfit can be used for visible surgical procedures through the camera shooting module.

What is claimed is: 
     
         1 . A puncture outfit comprising a camera shooting module with a light source, a puncture needle and a positioning puncture casing pipe that matches with the puncture needle; the camera shooting module is set at a head end of the puncture needle; the head end of the puncture needle is sheathed with a transparent cover that can cover the camera shooting module; the puncture needle is inserted in the positioning puncture casing pipe to make the transparent cover at the head end of the puncture needle slightly extend out of the positioning puncture casing pipe. 
     
     
         2 . The puncture outfit as set forth in  claim 1 , wherein the puncture needle comprises a needle guard, a handle, a protective rod and a reset spring; a sleeve joint part that matches with the needle guard is set on a front side wall of the handle; a tail end of the needle guard is sheathed on the sleeve joint part of the handle to make a head end of the needle guard form a single bevel blade; a tilting angle of the bevel of the single bevel blade is between 20˜70 degrees; a mounting rack that matches with the camera shooting module is mounted at a head end of the protective rod; mounting positions that match with the transparent cover are reserved at a head end of the mounting rack; a boss is set in the middle of the protective rod; a tail end of the protective rod is inserted in the needle guard to pass through the sleeve joint part and stretch into the handle; a clamping cap is set at the tail end of the protective rod to prevent the protective rod from moving out of the handle; the reset spring is sheathed at the tail end of the protective rod, and one end of the reset spring presses against the sleeve joint part while another end of the reset spring presses against the boss. 
     
     
         3 . The puncture outfit as set forth in  claim 2 , wherein the puncture needle further comprises a protection mechanism; the protection mechanism comprises an elastic arm; a head end of the elastic arm is fixed in the handle; a middle part of the elastic arm is set with a clamping position that can block the clamping cap to prevent the transparent cover from withdrawing back into the needle guard when the puncture needle is not used; a tail end of the elastic arm extends out from the front side wall of the handle to form a dial piece that presses against the positioning puncture casing pipe to make the clamping position move out of from the clamping cap when the puncture needle is matched with the positioning puncture casing pipe. 
     
     
         4 . The puncture outfit as set forth in  claim 3 , characterized in that the positioning puncture casing pipe comprises a casing pipe sheath, an upper cover, a sealing gasket, a check valve and a two-way valve; a buckle is set on an outer edge of the sealing gasket; a middle part of the sealing gasket has a conical bulge in a side; a through-hole that matches with the needle guard is set at a central position of the bulge; The through-hole has an interference fit with the needle guard; a hook is set on an outer edge of the check valve; two anti-pressing plates are set in the middle part of the check valve; the two anti-pressing plates are set oppositely in a closing shape to form an elongated gap that matches with the needle guard between their two adjacent end faces; a convex rib is set respectively on inner sides of the two anti-pressing plates to strengthen their structural strength; a cavity that matches with a contour of the check valve is formed at a tail end of the casing pipe sheath; a head end of the casing pipe sheath extends at its axial direction, and its outer side is set with a nodular and conical bulge; the head end of the casing pipe sheath is in a conical shape; the check valve is set in the cavity of the casing pipe sheath, and the hook of the check valve is buckled on an opening of the cavity; the sealing gasket is set on the opening of the cavity, and the buckle of the sealing gasket is buckled on the hook of the check valve; the upper cover is fastened on the opening of the cavity, and the sealing gasket and the check valve are positioned in the cavity of the casing pipe sheath; the two-way valve is fixed on the casing pipe sheath, and the two-way valve and the cavity of the casing pipe sheath are connected to each other. 
     
     
         5 . The puncture outfit as set forth in  claim 4 , characterized in that the transparent cover is a round pipe body; one end of the round pipe body is closed; a closing part of the round pipe body is in a beveled, spherical, conical or polygonal pyramid shape; when the closing part of the round pipe body is in a beveled shape, the tilting angle of its bevel is 20˜70 degrees.
