Description

Vein stripping and separating instrument

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a separation apparatus is peeled off to vein.

Background

At present, the superficial varicose vein operation of lower limbs has multiple modes, the longest application time is the most classical varicose vein stripping operation, rotary cutting operation, laser closing, radio frequency ablation, endoscopic surgery, sclerosing agent treatment and other modes are developed subsequently, but the operation modes all need the coordination of varicose vein punctiform stripping modes in many times, so varicose vein punctiform stripping is an essential link for completing the operation, usually, varicose punctiform stripping needs to make a plurality of 1-2cm or even longer incisions on lower limbs, doctors in partial western regions even leave a plurality of ten-centimeter-more' huge incisions on lower legs, and certain scars or even keloids can be left after the operation.

The vein denudation mainly comprises main denudation of a great saphenous vein and branch denudation of a varicose vein, wherein the vein denudation hook which is clinically applied and developed in recent years is mainly in a fish hook shape aiming at the branch denudation of the varicose vein, and the clinical application finds that the vein denudation hook is easy to hook out a vein together with nerves or adjacent tissues in the vein denudation process, so that side injury is caused.

SUMMERY OF THE UTILITY MODEL

For solving the problem that exists among the prior art, the utility model provides a separation apparatus is shelled to vein, this apparatus can effectively collude the vein through shelling the ware but can not collude unnecessary tissue such as normal tissue such as nerve, tendon, through the free vein pipe wall that the separator can be fine to cut off the vein and take the blood vessel out from the vein distal end by shovel portion is most advanced in the suitable position.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a vein denudation separation instrument comprises a handle, a separator and an denudation device, wherein the separator and the denudation device are connected with the handle.

The separator includes the first body of rod and separation shovel, first body of rod one end is connected on the stalk portion, and the other end is connected the separation shovel, the separation shovel shape is the cylinder of radial cross-section for "C" font, the first body of rod is connected the axial tip of separation shovel, the one end that the first body of rod was kept away from to the separation shovel is equipped with the blade face.

The stripper comprises a second rod body, one end of the second rod body is connected to the handle part, the cross section of the end part of the other end of the second rod body is gradually reduced along the length direction of the first rod body, the farthest end of the end part away from the handle part is in smooth transition of an arc surface, a hook part is arranged on the second rod body, and the hook part consists of two surfaces, inwards recessed, of the side surface of the second rod body.

In the structure, when a vein of a patient needs to be stripped, the stripper is firstly used for penetrating into the tissue of the patient, the vein wall is hooked out through the hook part, then the separator is used, the vein is sleeved into the separation shovel through the C-shaped notch, the separation shovel is pushed forwards along the vein direction, the vein wall can be well dissociated, the vein is cut off through the cutting edge at the far end of the separation shovel at a proper position, and the vein can be drawn out.

The stripper and the separator of the utility model have simple structure, only a skin incision of 2-3mm is needed to be opened on the skin of a patient, the vein of the patient can be stripped and separated, because the hook part of the stripper is composed of two surfaces which are sunken inwards and has no protruding structure, consequently can avoid the collateral damage, with patient's vein along with nervous or close on the tissue and collude in the lump when having avoided shelling, the free vein pipe wall in the propelling movement can be followed to the structure in separator "C" font cross-section, finally at distal end slope separation shovel, the blade of separation shovel distal end can cut off the vein, very convenient take the blood vessel out, traditional blood vessel relies on the hank to cut off or to break and takes out, the hank is broken or is broken and is carried out with the vascular pincers, can increase the operation surface of a wound, increase the collateral damage probability such as damage nerve or other tissues, the utility model discloses a separation shovel can reduce the collateral damage that brings in the operation process with shelling the ware.

Preferably, one end of the second rod body close to the hook part is provided with a radian.

The hook part operation is more convenient for the second rod body with the radian because the vein branch is not a straight line.

Has the advantages that:

1. the utility model discloses an exfoliator and separator simple structure only needs to open 2-3 mm's skin incision on patient's skin, can carry out the exfoliation and the separation of vein to the patient, because the hook portion of exfoliator constitutes for two faces that inwards cave in, does not have protruding structure, therefore can avoid vice damage, has avoided drawing off together patient's vein with nerve or near-on tissue when peeling off, the structure of separator "C" font cross-section can free the vein pipe wall in the propelling movement, finally at the distal end slope separation shovel, the blade of separation shovel distal end can cut off the vein, very convenient takes out the blood vessel, the utility model discloses a separation shovel and exfoliator can reduce the vice damage that brings in the operation process;

2. the distance between the position of the hook part and the farthest end is 2mm-3mm, so that a doctor can better grasp the position of the hook part during operation and can hook out the vein wall more accurately;

3. the flat strip handle part is convenient for a doctor to hold;

4. the anti-slip lines are arranged to facilitate the holding of a doctor;

5. the vein branch is not straight, so that the first rod body with the radian is more convenient to push the separation shovel along the vein wall;

6. the hook part operation is more convenient for the second rod body with the radian because the vein branch is not a straight line.
