Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a surgical auxiliary device for transperineal prostate puncture. Background Art

[0002] Prostate cancer ranks sixth in the incidence of male malignant tumors and is gradually affecting the life and health of middle-aged and elderly men. Ultrasound-guided transperineal prostate puncture is widely used to detect and diagnose prostate cancer.

[0003] During the puncture, the testicles need to be lifted up to expose the perineum. The current practice is to let the patient lift the testicles with both hands during the local anesthesia surgery. However, since most patients with prostate puncture are elderly, it is difficult for them to maintain the same body position for a long time, and there is a risk of insufficient exposure affecting the surgical field of view or affecting aseptic operation. On the other hand, there may be a variety of complications during the puncture, the most common of which is bleeding. Effective compression hemostasis after surgery has become the most important method to avoid complications. The basic method now is to stick gauze on the perineum and then sit forward on a hard bench to stop bleeding. However, the gauze is easy to fall off with movement, resulting in the puncture site not being in a sterile environment after surgery, which is prone to wound infection, or the patient's body position is limited and the puncture site cannot be effectively compressed. Summary of the invention

[0004] The purpose of the present invention is to provide a surgical auxiliary device for transperineal prostate puncture, which can realize the function of testicle lifting and fixation during the operation and the function of compressing the puncture point to stop bleeding after the operation.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The present invention provides a surgical auxiliary device for transperineal prostate puncture, comprising a scrotal bowl, wherein the scrotal bowl comprises a deformable matrix layer, the scrotal bowl comprises a convex surface and a concave surface, the side of the deformable matrix layer facing the convex surface is covered with a sterile dressing layer, and the edge of the scrotal bowl is connected with a butterfly patch A and a butterfly patch B.

[0007] Preferably, the deformable matrix layer is medical grade polyvinyl chloride (PVC) or thermoplastic elastomer (TPE).

[0008] In the present invention, the deformable matrix layer can be slightly deformed, which will not affect the postoperative movement and will not affect the compression effect.

[0009] Preferably, the sterile dressing layer is made of a transparent dressing, such as polyvinyl alcohol foam, which is semi-permeable and can be used to observe the wound condition without removal.

[0010] Preferably, a sterile dressing tearable protective film is provided on the sterile dressing layer.

[0011] Preferably, a deformable substrate layer tearable protective film is provided on the side of the deformable substrate layer facing the concave surface, and the butterfly-shaped sticker B is accommodated between the deformable substrate layer tearable protective film and the deformable substrate layer.

[0012] Preferably, the butterfly-shaped sticker B is connected and fixed to the concave edge of the scrotal bowl.

[0013] Preferably, the butterfly-shaped patch A is a tearable butterfly-shaped patch, comprising a connecting area and a main body area, wherein the connecting area is connected and fixed to the convex edge of the scrotal bowl, and a dotted hole is provided at the connection between the connecting area and the main body area to facilitate tearing off the main body area of ​​the butterfly-shaped patch A.

[0014] Preferably, the butterfly-shaped patch A and the butterfly-shaped patch B both include a non-woven fabric layer, a medical-grade glue layer is provided on the non-woven fabric layer, and a removable release paper is provided on the medical-grade glue layer.

[0015] In the present invention, the medical-grade glue layer can provide sufficient viscosity to ensure that the butterfly patch is fixed on the skin, and will not cause skin discomfort or allergic reaction when it needs to be torn off.

[0016] Preferably, the non-woven fabric is provided with air holes.

[0017] Preferably, the butterfly patch A includes wing a, wing b, wing c, and wing d in a cross design, and the butterfly patch B includes wing e, wing f, wing g, and wing h in a cross design, so that the auxiliary device provided by the present invention can be stably fixed on the skin.

[0018] Preferably, a buffer pad is provided on the contact surface between the scrotal bowl and the skin to reduce the pressure on the skin and improve the wearing comfort.

[0019] Preferably, the surgical assisting device is placed in a sterile package.

[0020] During transperineal prostate puncture, the auxiliary device can fully lift the testicles and firmly fix them, effectively solving the problem of the patient's inability to maintain body position. It can be used not only in local anesthesia surgery, but also in general anesthesia. After transperineal prostate puncture, continuous pressure can be applied to the perineum without affecting postoperative activities, and it contains sterile dressings, effectively avoiding postoperative wound infection or blood exudation.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention provides a surgical auxiliary device for transperineal prostate puncture. By setting a scrotal bowl with concave and convex surfaces and a butterfly-shaped patch, the function of testicle lifting and fixation can be achieved during surgery, and the function of compressing the puncture point to stop bleeding can be achieved after surgery.

[0023] (2) When the present invention is used during surgery, the four wings of the butterfly patch A are placed tightly against the lower abdominal wall and both sides of the thigh root, and the testicles are placed in the concave surface of the scrotal bowl, thereby achieving the function of lifting and fixing the scrotum during and after the transperineal prostate puncture surgery. The fixation is firm and not easy to fall off. When the patient uses this device, his hands can be freed during the operation, alleviating the discomfort caused by the fixed position.

[0024] (3) The present invention arranges a sterile dressing on the convex surface of the scrotal bowl and a hidden butterfly patch B on the concave surface. After the transperineal prostate puncture surgery, the butterfly patch A is torn off, the scrotal bowl is turned over, the butterfly patch B is opened, and the four wings of the butterfly patch B are pressed against the groin and both sides of the buttocks, so that the convex surface of the scrotal bowl is pressed against the puncture point to achieve compression and hemostasis. The patient can move freely after the surgery without affecting going to the toilet.

[0025] (4) The present invention is for non-invasive use outside the body and is a disposable product, one set per person, safe and sterile, and avoids cross infection.

[0026] (5) The present invention can select an appropriate size according to individual conditions, and can be used both during and after prostate surgery, and is widely used in transperineal prostate puncture under various anesthesia methods.

[0027] (6) The surgical assisting device designed by the present invention can switch between intraoperative and postoperative modes with one click, has a wide range of uses, is highly safe, easy to use, and highly comfortable. BRIEF DESCRIPTION OF THE DRAWINGS
