Description

A kind of operation retractor

Technical field

The present invention relates to medical instruments fields, specifically, the present invention relates to a kind of operation retractors.

Background technique

Retractor is a kind of surgical operating instrument, to retract tissue, appears surgical field of view, convenient for detecting and operating.Often Retractor has metal retractors and soft retractor.The common mechanical double pawl retractors of surgery are mostly stainless steel and titanium at present The production of the metal materials such as alloy, the advantage is that provide very big support force for operative incision and allow to sterilize repeatedly makes With.The disadvantage is that shape is fixed, wound is larger and larger to the repressive damage of tissue, such as periosteum injury, bone neurotrosis.But In some surgery minimally invasive surgeries（Such as intercostal small notch heart, the Lung operation of cardiothoracic surgery）In the middle, operative incision need not retract Device provides big support force, at this moment uses metal retractors, on the one hand can cause unnecessary soft tissue due to drawing energetically The even repressive damage of periosteum, or even the damage at neural position.On the other hand since the limitation of its shape can be to a certain degree Upper blocking surgical field of view, influences surgical procedure.In addition existing hand-held Wound retractor surgeon needs more in operation People cooperates, and one is inconvenient for use.

Summary of the invention

Technical problem to be solved by the invention is to provide it is a kind of can one man operation and the wide Wound retractor of applicability.

In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that：A kind of operation retractor, including spring And connector, two connector of spring bending are joined together to form annulus or elliptical ring by connector, the spring can be with Interception length as needed, the size for forming circle diameter adjustable in this way.

Preferably, the spring is flattened by roll squeezer.

Preferably, several deformation buttons of the upper setting of the annulus, the deformation button are stuck on annulus according to actual needs, As the increase annulus of deformation button can need to become ellipse according to wound.

Preferably, the deformation button generally " Z " font, deformation button is clamped on annulus on one side, another side be equipped with to Outer hook outstanding, hook can catch on the tissue of wound circumference, prevent retractor from shifting.

Preferably, the material of the annulus is stainless steel or titanium alloy.

Using technical solution of the present invention, beneficial effect below can be obtained：

Operation retractor shape of the invention is variable, can change the shape of retractor according to the shape of wound, set on retractor There is hook to catch on the tissue of wound circumference, prevents retractor from shifting.This retractor is easy to use, and retractor shape adjustment is good single People can be put into wound, be particularly suitable for first-aid patients and use.Do not stop among this retractor, doctor is facilitated to carry out next step Surgical procedure.

Specific embodiment

Below against attached drawing, by the description of the embodiment, to for example related each structure of a specific embodiment of the invention The works such as the shape of part, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle are further Detailed description.

As shown in Figure 1, 2, this operation retractor includes spring 1 and connector 2, and spring 1 is bent two connectors and passes through connector 2 It is joined together to form annulus or elliptical ring, spring 1 can according to need interception length, adjustable in this way to ultimately form annulus The size of diameter.As shown in Figure 4,5, spring 1 uses after being flattened by roll squeezer 5.Several deformation buttons 3 of the upper setting of annulus, Deformation button 3 is stuck on annulus according to actual needs, as the increase annulus of deformation button 3 can need to become ellipse according to wound Or other desired shape.

As shown in figure 3, deformation button 3 generally " Z " font, deformation button 3 are clamped on annulus on one side, another side be equipped with to Outer hook 4 outstanding, hook 4 can catch on the tissue of wound circumference, prevent retractor from shifting.The material of above-mentioned annulus is stainless Steel or titanium alloy change the big of retractor by changing the length of spring 1 using the length for facilitating spring 1 of metal material It is small, while metal material facilitates deformation and there is elasticity to be adapted to wound of various shapes.

Spring 1 is intercepted by suitable length according to the size of wound when use, is then flattened spring 1 using roll squeezer 5, 1 liang of connector of spring of flattening is bonded together using connector 2, deformation button 3 is clamped on annulus as needed, according to reality The shape needed increases the quantity of deformation button 3, while making annulus deformation with pliers the spring appropriate that be crushed that is bent.Such as it will The both ends retractor that deformation button 3 is clamped in annulus just deforms ovalisation, the hook 4 of the outside setting of deformation button 3, and hook 4 hooks Firmly the tissue of wound circumference prevents retractor from shifting.

Operation retractor shape of the invention is variable, can change the shape of retractor, retractor according to the shape of wound It is equipped with the tissue that hook 4 catches on wound circumference, prevents retractor from shifting.This retractor is easy to use, by retractor shape tune Section is good, and one can be put into wound, be particularly suitable for first-aid patients and use.Do not stop among this retractor, doctor is facilitated to carry out down The surgical procedure of one step.

The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
