Abstract

The utility model discloses a medical thread inserter which comprises a thread inserting ring (1) with a thread slot and a fixed seat (2), and also a compression rod (3) and a hinged support shaft (4). A bayonet (2-1) for clamping the thread inserting ring (1) is formed at the upper end of the fixed seat (2); the compression rod (3) is hinged with the fixed seat (2) through the hinged support shaft (4); the fixed seat (2) is clamped on a rack (5) of a retractor; a curved surface in contact with the rack (5) is arranged on the compression rod (3); and the compression rod (3) rotationally compresses the rack (5) through winding the hinged support shaft (4). The thread inserter provided by the utility model has the advantages that a surgeon easily clears complicated sutures in the operation on suturing an organ, the failure rate is reduced, the success rate of the operation is increased, and meanwhile, the operation time is greatly shortened; in addition, through the contact of the curved surface of the compression rod and the rack of the retractor, the thread inserter is assembled and disassembled very conveniently.

Description

Medical slot inserter

Technical field

This utility model relates to a kind of medical slot inserter, and sutural rule when being used for the cardiothoracic surgery open chest surgery and sewing up each organ belongs to the instrument field that surgical operation is used.

Background technology

Carry out less invasive techniques at present in the cardiothoracic surgery open chest surgery mostly; in operation through regular meeting run into big because of operation complex technology difficulty, sew up that pipeline is many, the corresponding suture intersection in each road causes being difficult for every pair of suture of clear reflection; the doctor need spend certain hour for putting each in order to stitching thread; this will prolong operating time, increases patient's misery.For this reason, begin to design the slot inserter that use is made up of holder and rule piece, ring.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of medical slot inserter easy to loading and unloading is provided, and this slot inserter can be avoided producing error in the operation during suture, shortens operating time, reduces patient's misery.

The technical scheme that realizes above-mentioned purpose is: a kind of medical slot inserter, comprise rule ring and holder with wire casing, also comprise compressor arm and hinging supporting shaft, the upper end of holder has the bayonet socket that blocks the rule ring, compressor arm is hinged by hinging supporting shaft and holder, holder is stuck on the tooth bar of retractor, has the curved surface that contacts with tooth bar on the compressor arm, and compressor arm can be by rotatably compressing tooth bar around hinging supporting shaft.

The rule ring is spring structure ringwise, and is made by metal material, and the upper end of holder has the bayonet socket that blocks the rule ring, and tightly blocks the rule ring by this bayonet socket.

The rule ring is hexgonal structure, and hexgonal structure is put together by six plastics rule pieces, and the bottom of rule ring is fixed with metal backing, the upper end welding of this metal backing and holder.

After adopting technique scheme, complicated each road stitching thread is put in order easily in operation, avoids error, and operating time shortens greatly, and the misery that has alleviated patient also alleviates a lot.Simultaneously, has the curved surface that contacts with tooth bar on the compressor arm, unclamp compressor arm, the curved surface on the compressor arm leaves tooth bar, just can easily slot inserter be unloaded down from retractor, during installation, holder is stuck on the tooth bar of retractor, compressor arm is rotated around hinging supporting shaft, the curved surface on the compressor arm can compress tooth bar, slot inserter can be fixed on the retractor, thereby loading and unloading easily.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in further detail.

Embodiment one

Shown in Fig. 1～3, a kind of medical slot inserter, comprise rule ring 1 with wire casing, rule ring 1 is spring structure ringwise, and make by metal material, also comprise holder 2, compressor arm 3 and hinging supporting shaft 4, the upper end of holder 2 has the bayonet socket 2-1 that blocks rule ring 1, and tightly block rule ring 1 by this bayonet socket 2-1, compressor arm 3 is hinged by hinging supporting shaft 4 and holder 2, holder 2 is stuck on the tooth bar 5 of retractor, has the curved surface that contacts with tooth bar 5 on the compressor arm 3, and compressor arm 3 can be by rotatably compressing tooth bar 5 around hinging supporting shaft 4.

The work process of this embodiment is as follows:

When the cardiothoracic surgery open chest surgery is sewed up each organ, after retractor retracts as requested, holder 2 is stuck on the tooth bar 5 of retractor, compressor arm 3 is by rotatably compressing tooth bar 5 around hinging supporting shaft 4, rule ring 1 tightly is stuck on the bayonet socket 2-1 of holder 2, after treating that the stitching thread slot inserter installs, the doctor can every pair of stitching thread very clear in pairs in order without any confusion be arranged in rule ring 1 around, every pair of suture ligature can not obscured; After stitching is finished, break compressor arm 3 off with the fingers and thumb and make it then holder 2 to be unloaded down from the tooth bar 5 of retractor rapidly by unclamping with tooth bar 5 around hinging supporting shaft 4 rotations.

Embodiment two

As Fig. 4, shown in 5, a kind of medical slot inserter, comprise rule ring 1 and holder 2 with wire casing 1-2, rule ring 1 is hexgonal structure, hexgonal structure is made up of the amalgamation of six plastics rule pieces, wire casing 1-2 is the plastics inserts, be installed on the rule ring 1, the bottom of rule ring 1 is fixed with metal backing 1-1, and the upper end welding of this metal backing 1-1 and holder 2 also comprises compressor arm 3 and hinging supporting shaft 4, compressor arm 3 is hinged by hinging supporting shaft 4 and holder 2, holder 2 is stuck on the tooth bar 5 of retractor, has the curved surface that contacts with tooth bar 5 on the compressor arm 3, and compressor arm 3 can be by rotatably compressing tooth bar 5 around hinging supporting shaft 4.Its loading, unloading principle is identical with embodiment one, in addition, plastics rule piece use certain hour or damage after have and advantage such as can change separately.
