Abstract

The utility model discloses a novel attract pipe, it is rational in infrastructure, can have the drag hook effect concurrently and prevent the tissue damage, can avoid attracting the pipe again and block up, mainly be applicable to neurosurgery, microsurgery or bone surgery. The head end of the suction pipe body adopts a right-angle arc inclined opening design and is matched with the flat antenna at the far end, so that tissue can be pulled, tissue fluid can be sucked, the operation visual field is conveniently exposed, two persons can be completed by one person, and the operation of a doctor is facilitated. And the oval control hole arranged on the suction tube handle can control the suction amount through the thumb, thereby improving the operation safety. The suction tube and the core are made of stainless steel materials and can be repeatedly used after high-temperature and high-pressure sterilization.

Description

Novel suction tube

Technical Field

The utility model relates to a suction tube, belonging to the field of medical apparatus.

Background

The suction tube is an essential important tool for surgical operations such as neurosurgery and microsurgery, and is mainly used for sucking blood and tissue fluid and exposing the operation field. The existing suction tube is always in a negative pressure state under the action of a negative pressure suction apparatus, so that a continuous suction state is achieved. The material of attracting the pipe is mostly formed with stainless steel or copper pipe preparation, and the body is mostly rectangular form or the tail end has certain radian a little, and the attraction mouth is mostly horizontal form crew cut opening. In neurosurgery or orthopedic surgery, when a main surgeon needs to expose a fibrous ring to excise an intervertebral disc, an assistant needs to pull a nerve root and a dural sac open towards the opposite side by using a nerve retractor, the main surgeon needs to hold a suction tube with one hand for continuous suction, and hold a scalpel with the other hand for incising the fibrous ring; because the diameter of the operation visual field is sometimes less than 1 cm, the operation under a microscope is needed in most cases, the operation of a main surgeon is seriously affected because the assistant is difficult to draw the nerve root and the dura mater sac or is not drawn in place, the nerve root or the dura mater sac can be damaged by a little carelessness, if the suction tube used by the main surgeon also has the function of a nerve drag hook, the whole operation process of cutting the intervertebral disc can be independently completed by one doctor, the operation safety is greatly improved, and the operation time is shortened.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the suction tube has reasonable structure, can have the function of a draw hook to prevent tissue damage and can avoid the blockage of the suction tube, and is mainly suitable for neurosurgery, microsurgery or fracture operation.

Attract pipe, including body, pipe handle and core, attract pipe handle welding at the body end, have the control hole on the pipe handle, the pipe handle afterbody is the echelonment structure of being connected with the vacuum aspiration ware, the body head end is right angle arc, the arc summit department is for attracting the pipe opening part, the mouth of pipe distal end is the platykurtic feeler, the feeler near-end is in the same place with the welding of body head end, the end is the arc, upwarps slightly, the core inserts from attracting the pipe tail end, can reach and attract the pipe opening part, the body adopts stainless steel material.

The control hole is in an oval shape, and the size of the control hole blocked by a thumb can be used for adjusting the suction flow of the suction tube in the suction process. The core is made of stainless steel materials, the tail end of the core is of a circular structure, and the core is convenient to hold and used for dredging the inner cavity of the pipe body and preventing the inner cavity of the pipe body from being blocked. The opening direction of the control hole and the flat antenna direction at the far end of the pipe orifice are opposite directions, so that the operation is convenient.

Compared with the prior art, the utility model the advantage that has as follows:

this attract pipe is rational in infrastructure, attracts body head end to adopt the oblique opening design of right angle arc, and cooperation distal end platykurtic feeler both can tractive tissue, can attract tissue fluid again, conveniently exposes the operation field of vision, and the work of two people can be accomplished to alone, the main sword doctor of being convenient for operates. Moreover, the oval control hole arranged on the suction tube handle can control the suction amount through the thumb, so that the operation safety is improved. The suction tube and the core are made of stainless steel materials and can be repeatedly used after high-temperature and high-pressure sterilization.

Detailed description of the invention

As shown in figure 1, the suction tube comprises a tube body 1, a suction tube handle 2, an antenna 6 and a core 7, wherein the suction tube handle 2 is welded at the tail end of the tube body 1, the suction tube handle 2 is provided with a control hole 4, the tail part of the suction tube handle 2 is a ladder-shaped structure 3 connected with a negative pressure suction apparatus, and the core 7 is inserted into an opening 5 of the suction tube mouth from the tail part of the suction tube handle 2.

Wherein: the control hole is designed in an elliptical shape, and the suction flow of the suction tube can be adjusted by blocking the size of the control hole by a thumb in the suction process; tissues can be retracted towards the opposite side by attracting the antenna at the head end of the tube body, and the operation visual field is exposed.

In the using process, the tail part of the suction tube handle 2 is connected with the negative pressure suction apparatus, a doctor holds the front end of the suction tube handle 2 by hand, the thumb blocks the control hole 4, the suction amount can be adjusted by controlling the size of the control hole 4 blocked by the thumb in the suction process, and tissue damage or blockage of the suction tube is prevented; the tissue can be pulled to the opposite side by adjusting the antenna direction at the front end of the suction tube body, when the inner cavity of the tube body 1 is blocked by a blood clot or a bone block, the core 7 can be used for dredging, and after the operation is completed, the suction tube can be repeatedly used after high-temperature and high-pressure disinfection.
