Abstract
The utility model belongs to the field of medical surgical operation appliances, wherein copper is designed to be used for manufacturing decompressional substernal space spreaders. The utility model comprises a head (1), a rod (2) and a handle (3).The external form of the head is oblate,and the maximum outer diameters of the head are that the length is 4cm, the width is 2cm, and the thickness is 0.6cm, and a pressure-relief vent (4) with 1cm diameter is arranged inside, which has the function of carrying wire, reducing pressure, facilitating the welding of a joint (5) of the rob and the head, and reducing the weight of the head. The rod (2) is made of a copper tube with a section diameter of 0.5cm which has good flexibility and tenacity, which can be bent to different radians according to the needs of operations, and the left and right movement of the rod enlarges clearance to an ideal width.
Description
This utility model belongs to the medical surgical instrument field
In the thoracic surgery clinical practice, the doctor is sometimes for the needs of operative treatment, often the retrosternal space with the patient enlarges, so that make substitute organs such as stomach or colon arrive cervical region through retrosternal space smoothly, retrosternal space expander (Fig. 1) commonly used at present because of its head is roomy, and does not have decompressing effect, damage pleural space easily, the chance that iatrogenic pneumothorax occurs is more.
The purpose of this utility model is that a kind of novel operation apparatus that retrosternal space enlarges of finishing will be provided.
The purpose of this utility model is achieved in that decompression type retrosternal space expander, and designing institute is copper with material, because copper has certain rigidity, good flexible is arranged again, can it be curved different radians according to the needs of operation.This utility model is made up of three parts, i.e. head, bar, handle.Head be shaped as flat ellipse, its maximum outside diameter is respectively: long 4cm, wide 2cm, thick 0.6cm.In the vent of diameter 1cm is arranged, have and take line, alleviate head weight, be convenient to the welding of head and bar and the effect of buffering negative pressure, less because of its head volume, be easy to come out from fovea jugularis.The buffering suction function of vent is achieved in that in use, because of about " Dragsaw type " action produces negative pressure, copper pipe that this hole is attached thereto and extraneous communicating, thus cushion negative pressure.Bar is the copper pipe of cross section diameter 0.5cm, and the pliability of copper pipe is good, can it be curved different radians according to the operation needs.After in a single day retrosternal space is got through, available hand-held head, handle, left and right sides pusher rod and make gap enlargement to required width.Handle is the afterbody of bar and it is curved equilateral triangle, is convenient to grip.
This utility model excuse portion volume is less, is easy to pass retrosternal space and comes out from fovea jugularis.In the break-through process because of vent is arranged, so do not have negative pressure, very light to the surrounding tissue damage, after head passes from fovea jugularis, can make gap enlargement to desirable width with passing about bar.
Concrete structure of the present utility model has following examples and accompanying drawing thereof to provide.
Fig. 1 is the retrosternal space expander
Fig. 2 is a structure chart of the present utility model
The junction of 1. 2. bar 3. handles 4. vents 5. bars and head among the figure
Head does not have vent in Fig. 1
In the embodiment of Fig. 2 institute, head (1) portion is shaped as flat ellipse, and its maximum outside diameter is respectively: long 4cm, wide 2cm, thick 0.6cm, in the vent (4) of diameter 1cm is arranged, have take line, alleviate head weight, effect that head (1) and bar (2) welded and cushioned negative pressure easily.Head (1) and bar (2) junction (5), by welding, solid, firm.Bar (2) is drawn materials has copper pipe for cross section diameter 0.5cm.The buffering suction function of vent is achieved in that in use, because of about " Dragsaw type " action produces negative pressure, copper pipe that this hole is attached thereto and extraneous communicating, thus cushion negative pressure.
Claims (1)
- Decompression type retrosternal space expander is linked in sequence by head (1), bar (2), handle (3), it is characterized in that: head (1) be shaped as flat ellipse, its maximum outside diameter is respectively: long 4cm, wide 2cm, thick 0.4cm, in the vent (4) of diameter 1cm is arranged, vent (4) is that bar (2) is connected with the copper pipe of cross section diameter 0.5cm, and junction (5) adopt welding manner.
