Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a surgical retractor. Background Art

[0002] A retractor, also known as a retractor hook, is used to retract tissues to expose the surgical area for easy exploration and operation. It can be divided into two categories: hand-held retractors and automatic retractors. Small retractors can omit the process of "lifting the skin", reducing the burden on the assistant holding the retractor and being flexible to use. In surgical operations, since high-frequency electrocautery, ultrasonic scalpel, saw blade, and high-speed drill bit will vaporize tissue proteins and fats to generate gaseous substances, that is, surgical smoke, which is also called aerosol or cautery smoke. It will not only block the surgical field of view but also pose a threat to the health of medical staff. In addition to using a smoking device to directly suck away the smoke at the smoke-generating position, in order to continuously reduce the smoke as much as possible, in the prior art, a smoking tube is provided on the retractor to continuously guide and suck away the smoke. However, in the existing retractors with smoking functions, the smoking tube is generally set on the side of the retractor or extends out of the retractor, and most of them are circular. Whether the smoking tube is routed along the side of the retractor or extends out, it is likely to affect surgical operations, and the fixing effect of the circular smoking tube to the retractor is not good.

[0003] Therefore, there is an urgent need for a surgical retractor to solve the above problems. Summary of the Utility Model

[0004] Based on the above, the purpose of the utility model is to provide a surgical retractor with better pulling force and stability, a relatively smooth structural streamline, and less interference to the operation.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0028] Such as Figure 1As shown in the figure, this embodiment provides a surgical retractor, which includes a retractor part 1, a smoke suction tube 2 and a handle part 3. The retractor part 1 includes a hook arm 11, a connecting arm 12 and a carrier arm 13. The hook arm 11 and the carrier arm 13 are arranged at a relative interval, and the connecting arm 12 is connected between the hook arm 11 and the carrier arm 13; the smoke suction tube 2 is arranged on the side of the carrier arm 13 facing away from the hook arm 11. The cross-sections of the carrier arm 13 and the smoke suction tube 2 are both rectangular. One end of the smoke suction tube 2 is a smoke inlet 210, and the other end is a smoke outlet 220. The smoke inlet 210 faces the connecting arm 12 and is obliquely arranged. The upper edge of the smoke inlet 210 is closer to the smoke outlet 220 than the lower edge; one end of the handle part 3 is connected to the end of the carrier arm 13 facing away from the connecting arm 12. The handle part 3 can be used to connect an external clamping device. For example, one end of a fixing clamp clamps the handle part 3, and the other end is fixed on the operating table. By arranging the rectangular smoke suction tube 2 on the side of the carrier arm 13 facing away from the hook arm 11, not only can the structural strength of the surgical retractor be enhanced, ensuring the pulling ability and stability, but also the overall shape of the smoke suction tube 2 and the carrier arm 13 can be made consistent, making the structural integrity and compactness of the surgical retractor better; at the same time, by arranging the oblique smoke inlet 210, while being able to continuously suck surgical smoke, reducing the assistant's work, ensuring sufficient exposure of the surgical field and the health of medical staff, the overall structure of the surgical retractor has a smooth streamline, conforms to the surgical movement trend, and can effectively avoid interfering with the operation. Compared with the prior art where the smoke suction tube is located on the side and not only occupies the pulling part and comes into contact with the pulling part, etc., this surgical retractor has better pulling stability and less interference with the operation and the pulling part.

[0029] In this embodiment, the hook arm 11 has a plate-like structure, which increases the contact area with the pulling part, has better structural strength and stability, and is not easy to deform or damage the human pulling part during the pulling process.

[0030] Preferably, the retractor part 1 is made of disposable medical rigid PVC material, which has a lower cost and better structural strength. Optionally, the hook arm 11, the connecting arm 12 and the carrier arm 13 are integrally formed into a U-shaped structure. As Figure 2 shown, the connecting arm 12 is arc-shaped, or as Figure 1 shown, the connection between the hook arm 11 and the connecting arm 12 is arc-shaped, and the connection between the connecting arm 12 and the carrier arm 13 is arc-shaped. The overall structure of the retractor part 1 is relatively smooth, and it can undergo a certain degree of elastic deformation under force and is not easy to break, etc., and the force-bearing effect is better.

[0031] Specifically, the smoking tube 2 includes a main body section 21 and a connecting section 22. The main body section 21 is a rectangular tube, and the connecting section 22 is a circular tube. One end of the circular tube facing away from the rectangular tube is the smoke outlet 220, which is used to connect to an external smoking device. The overall structure of the rectangular tube is similar to that of the carrier arm 13, ensuring the structural compactness and integrity of the surgical retractor. The circular tube is convenient for connecting to an external smoking device. By providing suction power through the smoking device, surgical smoke can be attracted and flow into the smoking tube 2 and the external smoking device. For example, the external smoking device can be, but is not limited to, a negative pressure pump.

[0032] Preferably, the smoking tube 2 is made of disposable medical plastic, which has a low cost and can be discarded after one use, ensuring surgical hygiene.

[0033] Furthermore, the handle portion 3 includes an elastic section 31 and a clamping section 32 that are connected end to end. One end of the elastic section 31 facing away from the clamping section 32 is connected to the end of the handle portion 3 facing away from the carrier arm 13, and the elastic section 31 can be stretched along the length direction of the handle portion 3 under force. The clamping section 32 is for being clamped by a clamping device. When the surgical retractor holds the retracting site and the clamping device holds the surgical retractor, the elastic section 31 is stretched, making the flexibility of using the surgical retractor better, that is, it can be applicable to different fixed lengths, and can avoid causing harm to the human retracting site due to overly rigid retraction while ensuring sufficient retracting force. Exemplarily, the elastic section 31 is a thermoplastic polyurethane elastomer, that is, made of elastic TPU material, which has good strength and elasticity.

[0034] Preferably, an anti-slip structure is provided on the clamping section 32 to increase the friction with the clamping device, thereby improving the clamping stability. Exemplarily, the anti-slip structure is anti-slip strips ¾ 1 that are spaced apart and protrude on the clamping section 32 along the length direction of the clamping section 32. The structure is simple, easy to mold, and has a low cost.

[0035] In this embodiment, the surgical retractor can be provided with multiple models to be applicable to different surgical sites. To facilitate the distinction of different models of surgical retractors, a model identification color layer is provided on the retractor portion 1 and / or the handle portion 3. The model of the surgical retractor is distinguished by the color of the model identification color layer. For example, a surgical retractor of one model has a yellow layer provided on the handle portion 3, and a surgical retractor of another model has a green layer provided on the handle portion 3, etc., so as to quickly distinguish the models of the surgical retractors.

[0036] The surgical retractor provided in this embodiment can continuously suck surgical smoke, making the surgical field of view clear, reducing the surgical smoke inhaled by medical staff, ensuring the health of medical staff, and reducing the retracting burden on the assistant; at the same time, the surgical retractor has a low cost, is flexible and convenient to use, has a stable structure, a smooth overall streamline, and less interference to the surgery, and can be applicable to all surgical departments.
