Description

Technical Field

[0001] This utility model relates to the field of surgical drapes, and more particularly to a percutaneous endoscopic lumbar discectomy drape. Background Technology

[0002] Currently, percutaneous endoscopic discectomy has become an important surgical procedure in spinal surgery. It performs lumbar spine-related surgeries in a water-based environment with minimal invasiveness. However, precisely because it is performed in a water-based environment, water management and control become a challenge. Conventionally, negative pressure suction devices are used to aspirate various fluids generated during the procedure. Alternatively, medical staff may use cleaning materials to form a U-shaped drainage channel around the edge of the surgical drape opening, allowing surgical waste fluid to drain into a specialized waste collection bag.

[0003] The prior art disclosed in application number 202323413027.7 is a disposable sterile surgical membrane for intraoperative use, comprising: a fixation sheet and a drainage bag. The fixation sheet has an operating port and an adhesive layer on its back. A U-shaped airbag is arranged on three sides of the fixation sheet around the operating port. An air inlet is arranged on the U-shaped airbag, and a removable sealing cap is connected to the air inlet. One side of the drainage bag is connected to one side of the fixation sheet. A guide tube is arranged at the bottom of the drainage bag. The fixation sheet is fixed to the surgical drape. The operating port is arranged around the opening of the surgical drape. Inflation is performed into the U-shaped airbag. Surgical waste fluid generated during the operation flows from the operating port into the drainage bag and flows out from the guide tube. The guide tube is connected to a waste fluid container. However, leakage of fluid can still easily occur because there is a gap between the "U"-shaped airbag and the drainage bag. The human back has a curved structure, and the gap between the "U"-shaped airbag and the drainage bag will be located at different positions on the curve of the patient's back depending on the patient's body size and surgical position. When the gap between the "U"-shaped airbag and the drainage bag is located at the sloping curve, fluid is prone to leaking out from the gap. Utility Model Content

[0004] This invention provides a percutaneous endoscopic lumbar discectomy drape to solve the problem of easy leakage of liquid from surgical drapes in the prior art.

[0005] This utility model provides a percutaneous endoscopic lumbar discectomy drape, including a surgical drape with a surgical opening, a U-shaped air bag and a collection bag. The sidewalls of the U-shaped air bag and the collection bag are fixedly connected to the surgical drape. The U-shaped air bag has an inflation chamber and an inflation port communicating with the inflation chamber. A sealing plug is inserted into the inflation port. One end of the U-shaped air bag is positioned opposite the other end of the collection bag. The end of the U-shaped air bag extends into the port of the collection bag, and one end of the collection bag extends between the U-shaped air bag and the surgical drape.

[0006] Furthermore, an adhesive tape is connected to the side of the collection bag away from the surgical drape, and the collection bag is bonded and fixed to the outer wall of the U-shaped inflatable bag by the adhesive tape.

[0007] Furthermore, the end of the collection bag furthest from the U-shaped inflatable bag is connected to a drain valve.

[0008] Furthermore, a drain extension pipe is connected to the outlet of the drain valve.

[0009] Furthermore, the collection bag is made of a transparent material.

[0010] Furthermore, an adhesive ring is attached to the side of the surgical drape away from the U-shaped inflatable bag, and the surgical opening is arranged within the adhesive ring.

[0011] Furthermore, an air supply pipe is fixedly connected to the U-shaped inflatable bag, the air supply pipe is connected to the inflation chamber, and a one-way valve is connected to the air supply pipe, the one-way valve only allows gas to enter the inflation chamber.

[0012] Furthermore, a placement pocket is fixedly connected to the surgical drape, and the U-shaped inflatable bag is located between the placement pocket and the collection bag.

[0013] Furthermore, a placement pocket is detachably connected to the surgical drape, and the U-shaped inflatable bag is located between the placement pocket and the collection bag.

[0014] The beneficial effects of this invention are as follows: Gas is introduced into the inflation chamber through the inflation port. After the U-shaped inflation bag is filled, it forms a blocking structure with one open end at the edge of the surgical opening. The fluid generated at the surgical site is confined to the open port of the U-shaped inflation bag to flow out. Since one end of the open port of the U-shaped inflation bag extends into the port of the collection bag, all the fluid is guided into the collection bag, thus preventing leakage. At the same time, the inflation of the U-shaped inflation bag supports the port of the collection bag, thereby improving the stability of the collection bag in collecting fluid.

[0023] The following is combined with Figures 1-4 This invention describes a percutaneous endoscopic lumbar discectomy (PELD) drape, comprising a surgical drape 1 with a surgical opening 11. The drape also includes a U-shaped air bag 2 and a collection bag 3, the sidewalls of which are fused to the surgical drape 1. The U-shaped air bag 2 has an inflation chamber 21 and an inflation port 22 communicating with the inflation chamber 21, with a sealing plug 221 inserted into the inflation port 22. One end of the U-shaped air bag 2 is positioned opposite the other end of the collection bag 3, with the end of the U-shaped air bag 2 extending into the port of the collection bag 3, and the other end of the collection bag 3 extending between the U-shaped air bag 2 and the surgical drape 1.

[0024] Specifically, such as Figure 1 , Figure 2 As shown, a U-shaped air bag 2 is arranged around the surgical opening 11, with an open port 23 at one end. The port of the collection bag 3 faces the open port 23, and one end of the open port 23 of the U-shaped air bag 2 extends into the port of the collection bag 3. The surgical drape 1, the U-shaped air bag 2, and the collection bag 3 are all made of waterproof material. The side of the U-shaped air bag 2 and the collection bag 3 closest to the surgical drape 1 is fixedly connected to the surgical drape 1 by adhesive or welding.

[0025] When using a percutaneous endoscopic lumbar drape, the drape is laid on the patient's back with the open port 23 facing the side of the back, and the surgical opening 11 located at the site of the procedure. Gas is introduced into the inflation chamber 21 through the inflation port 22. After the U-shaped inflation bag 2 is filled, it forms a blocking structure with one open end at the edge of the surgical opening 11. The sealing plug 221 is inserted into the inflation port 22 to seal the inflation chamber 21. Figure 3 As shown, fluid generated at the surgical site is confined to the open port 23 of the U-shaped air bag 2. Since one end of the open port 23 of the U-shaped air bag 2 extends into the port of the collection bag 3, all the fluid is guided into the collection bag 3, thus preventing leakage and ensuring a dry environment in the non-surgical area. Simultaneously, the inflation of the U-shaped air bag 2 supports the port of the collection bag 3, thereby improving the stability of fluid collection in the collection bag 3.

[0026] In some alternative embodiments, the port of the collection bag 3 is connected to an adhesive tape 4 on the side away from the surgical drape 1, and the collection bag 3 is bonded and fixed to the outer wall of the U-shaped inflatable bag 2 by the adhesive tape 4.

[0027] Specifically, adhesive tape 4 is set as a single-sided adhesive, such as... Figure 1 As shown, one end of the adhesive tape 4 is adhered to the outer wall of the collection bag 3, and the other end of the adhesive tape 4 is adhered to the outer wall of the U-shaped air bag 2, thereby achieving adhesion and fixation of the U-shaped air bag 2 and the collection bag 3 on the side away from the surgical drape 1 through the adhesive tape 4. In another optional embodiment, the adhesive tape 4 is set as double-sided adhesive, and the adhesive tape is located between the inner wall of the collection bag 3 and the outer wall of the U-shaped air bag 2, thereby achieving adhesion and fixation of the U-shaped air bag 2 and the collection bag 3 on the side away from the surgical drape 1 through the adhesive tape 4, improving the stability of the connection between the U-shaped air bag 2 and the collection bag 3.

[0028] In some optional embodiments, the end of the collection bag 3 furthest from the U-shaped inflatable bag 2 is connected to a drain valve 5, and a drain extension pipe 51 is connected to the outlet of the drain valve. Specifically, as shown... Figure 2As shown, the drain valve 5 is connected to the end of the collection bag 3 away from the U-shaped air bag 2. By opening the drain valve 5, the liquid collected in the collection bag 3 passes through the drain valve 5 and is discharged through the drain extension tube 51. The drain extension tube 51 drains the discharged liquid to avoid excessive weight on one side of the percutaneous endoscopic lumbar discectomy drape, and to prevent the surgical drape 1 from shifting due to the weight of the collection bag 3, thus affecting the surgery.

[0029] In some alternative embodiments, the collection bag 3 is made of transparent material, such as transparent plastic. When it is necessary to observe the color of the liquid or when the liquid is being bagged, the drain valve 5 is closed, and the collected liquid is observed through the collection bag 3.

[0030] In some alternative embodiments, an adhesive ring 12 is adhered to the side of the surgical drape 1 away from the U-shaped inflatable bag 2, and the surgical opening 11 is disposed within the adhesive ring 12. Specifically, the adhesive ring 12 is located on the side of the surgical drape 1 away from the U-shaped inflatable bag 2, such as... Figure 4 As shown, the adhesive ring 12 is arranged around the surgical opening 11, and the surgical drape 1 is adhered to the patient's skin through the adhesive ring 12.

[0031] In some alternative embodiments, such as Figure 1 As shown, an air supply pipe 7 is fixedly connected to the U-shaped inflatable bag 2. The air supply pipe 7 is connected to the inflation chamber 21, and a one-way valve 71 is connected to the air supply pipe 7. The one-way valve 71 only allows gas to enter the inflation chamber 21. Specifically, the air supply pipe 7 is connected to the inflation chamber 21. When the U-shaped inflatable bag 2 leaks air, air is supplied to the inflation chamber 21 through the air supply pipe 7. The one-way valve 71 only allows gas to enter the inflation chamber 21, preventing the inflation chamber 21 from leaking out from the air supply pipe 7.

[0032] In some alternative embodiments, a placement pocket 6 is fixedly connected to the surgical drape 1, and a U-shaped inflatable bag 2 is located between the placement pocket 6 and the collection bag 3.

[0033] Specifically, such as Figure 1 As shown, the opening of the placement pocket 6 faces the U-shaped inflatable bag 2, which is located between the placement pocket 6 and the collection bag 3. The placement pocket 6 is fixed to the surgical drape 1 by adhesive or fusion. The placement pocket 6 is used to place commonly used instruments during surgery. The commonly used instruments and the collection bag 3 are located on both sides of the surgical opening 11, which facilitates the operation of the surgical staff when retrieving instruments and also balances the weight of the collection bag 3, improving the stability of the surgical drape 1.

[0034] In some alternative embodiments, a placement pocket 6 is detachably connected to the surgical drape 1, with a U-shaped inflatable bag 2 located between the placement pocket 6 and the collection bag 3. Specifically, the placement pocket 6 is detachably connected to the surgical drape 1 via Velcro, allowing for position adjustment of the placement pocket 6 on the surgical drape 1.

[0035] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
