Abstract
The utility model relates to an improved puncture outfit. The improved puncture outfit solves the problem that an existing puncture outfit is not reasonable enough in design. The improved puncture outfit comprises a puncture cannula base, a puncture cannula, a sealing cap and a conversion cap. A valve is arranged outside the puncture cannula base through an installing structure. A side groove formed in the side face of the upper portion of the puncture cannula base is included. A pressing body which can horizontally move along the side groove is arranged in the side groove. At least two horizontally-arranged locking and inserting bodies are arranged at the inner end of the pressing body. At least two positioning pins are arranged in the conversion cap. The locking and inserting bodies correspond to the positioning pins in a one-to-one mode. Clamping structures are arranged between the locking and inserting bodies and the corresponding positioning pins. When the pressing body drives the locking and inserting bodies to move inwards in the axial direction of the side groove, the positioning pins can be separated from the locking and inserting bodies. The improved puncture outfit has the advantages that double side simultaneous fixation or separation can be achieved, air does not leak between the conversion cap and the cannula base, stability is high, the stability of the valve is high, the improved puncture outfit is convenient to open or close, the sealing performance of the sealing cap is high, and the improved puncture outfit does not easily contaminate visualized instruments.
Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of modified form perforator.
Background technology
In Wicresoft's medical-therapeutic treatment of human body operation, once find focus in body, need operation or excision, in operation process, what first need application is perforator, perforator is a kind ofly to pierce through stomach wall and for other operating theater instruments provide the operating theater instruments that enters body cavity passage, belong to a kind of Minimally Invasive Surgery apparatus.Perforator generally includes as the receiver of other operating theater instruments admission passages and is arranged on the switch cap of receiver and through the puncturing lever in described receiver and switch cap.First, for transdermal, first cut epiderm skin with scalpel, then utilize puncturing lever transdermal and enter body cavity together with receiver and switch cap, then extract puncturing lever out, receiver and switch cap just can be used as various apparatuses and instrument is introduced intraperitoneal and provide aeration to make stomach wall be elevated to the passage of organ top.
In existing perforator use procedure, switch cap is connected with receiver adopting the bilateral buckle structure of pressing to be fixedly linked, operation inconvenience when use, cannot realize bilateral fixing or disengaging simultaneously, dismounting inconvenience, and in the time that operating theater instruments is passed switch cap and receiver, due to the angle difference of operating theater instruments inclination, easily make that switch cap is relative with receiver to be swung, thereby cause switch cap to be connected defective tightness with receiver, cause the generation of gas leak phenomenon, in addition, existing valve mostly is split-type structural, poor stability, easily produce and rock, sealing effectiveness is poor, easily produce gas leakage or the phenomenon of leakage, the unlatching of valve or shutoff operation inconvenience structural strength are low, when perforator sealing cap uses simultaneously, apparatus insertion resistance is large, sealing effectiveness is poor, easily produce gas leak phenomenon, apparatus easily causes sealing cap turnup while extraction out, in the time utilizing perforator to carry out visual Minimally Invasive Surgery, due to liquid such as the remaining blood of meeting in sealing cap, blood remaining in the time that visual apparatus passes sealing cap easily pollutes the photographic head of visual apparatus end, cause operation carry out not smooth.
The problem existing in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of sleeve assembly [application number: 201320291219.2] of perforator, and the housing at this sleeve assembly top comprises: switch cap and receiver that upper-lower seal coordinates; Described receiver comprises: bowl bodies, sealing are fixed on the annular cover plate at this bowl bodies top; On the lateral wall of described annular cover plate, be evenly distributed with at least two for the mounting groove of three-back-shaped snap close is set; The medial wall of three-back-shaped snap close is provided with spring; On the end face of described annular cover plate, be distributed with the interface with described mounting groove up/down perforation; The bottom of described switch cap is extended with multiple for inserting respectively the dead bolt of described interface downwards, the inner side of this dead bolt has locked groove, after this dead bolt is successively through the through hole on described interface, three-back-shaped snap close, under the effect of described spring, described locked groove secure fit is in the through hole of described three-back-shaped snap close.
Such scheme has solved the problem of existing perforator switch cap and receiver dismounting inconvenience to a certain extent, but this scheme still exists: use inconvenience, bilaterally cannot lock simultaneously or depart from, switch cap and easily relative swing of receiver, thereby cause switch cap to be connected defective tightness with receiver, cause gas leak phenomenon, visual apparatus is easily contaminated through sealing cap photographic head, the problem of the unlatching of valve or shutoff operation inconvenience.
