Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a foraminal endoscopic surgery film device for preventing the wetting of the sterile area. Background Art

[0002] Foraminal endoscopic surgery is a technique for minimally invasive treatment of lumbar disc herniation. A working channel is established at the posterior lumbar intervertebral foramen of the patient, and then an endoscope and special surgical instruments are used for surgical operations. It belongs to minimally invasive surgery, with many advantages such as small incision, less trauma, fast recovery, short hospital stay, and relatively few complications. However, a large amount of isotonic fluid perfusion is required during foraminal endoscopic operation to wash the medullary cavity to ensure a clear surgical field for the surgeon. Moreover, during the operation, since the surgeon constantly changes the operation channel and instruments, the irrigation fluid often overflows from the operation channel opening, wetting the surgical drape, even the patient's bedding, the surgeon's clothes and pants, and the floor of the operating room. This causes the patient's body temperature to drop, reduces the comfort of the doctor and the patient, results in a large amount of water accumulation on the floor, increases the risk of infection and does not meet the requirements of infection control, and there are certain safety hazards. In the past, in order to prevent the intraoperative irrigation fluid from overflowing, ordinary surgical films and craniotomy films were usually used for pasting, but the effect was not good. The utility model patent with the publication number CN215840814U discloses an irrigation fluid drainage device, which includes: a water blocking member that encloses to form a water blocking area, and the water blocking member is provided with a drainage notch communicating with the water blocking area; a waterproof film for fitting the skin of the surgical object located in the water blocking area, the waterproof film contacts the water blocking member, and the part of the waterproof film through which the surgical instrument passes is within the water blocking area. During the operation, the waterproof film fits the skin of the surgical object located in the water blocking area, and two surgical instruments pass through the waterproof film within the water blocking area and are inserted into the human body. Two holes are formed on the waterproof film and the human body respectively for the two surgical instruments to pass through. The irrigation fluid enters the human body from one hole and flows out to the water blocking area from the other hole. The water blocking member can prevent the irrigation fluid from overflowing everywhere, and the irrigation fluid flows out from the drainage notch to a predetermined position. Thus, the outflow direction of the irrigation fluid can be limited, and the influence of the irrigation fluid overflowing everywhere on the progress of the operation can be avoided. However, in the above scheme, the water blocking and drainage part and the waste liquid receiving part are separated, and there are the following problems: 1. When installing and using, the drainage part and the waste liquid receiving part need to be docked well, and a connecting structure needs to be additionally provided to ensure reliable connection and prevent the waste liquid receiving part from falling off and leaking; 2. There is no support at the opening of the waste liquid receiving part, and it is easy to collapse due to wet water, resulting in deformation of the opening and unreliable water receiving. Therefore, it is necessary to invent a foraminal endoscopic surgery film for preventing the wetting and contamination of the sterile area to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a foraminal endoscopic surgery film device for preventing the wetting of the sterile area, aiming at the above problems, and solving the technical problems of the traditional foraminal endoscopic surgery film drainage device being separately arranged and difficult to install, and the opening of the water collecting bag having no support and being easy to deform.

[0004] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0005] An intervertebral foramen mirror surgery film device for preventing the wetting of the sterile area, comprising a film body, a water retaining fence and an open half-ring; one side of the film body is set as a sticking area, and the other side is provided with a water collecting bag; one side edge of the sticking area is integrally connected with the opening edge part of the water collecting bag, one end face of the sticking area is set as a sticking surface, and the other end face is fixedly provided with the water retaining fence. A surgical window is also arranged on the film body, and the surgical window is located in the area surrounded by the water retaining fence and the opening edge of the water collecting bag; the water retaining fence is provided with a side opening facing the direction of the water collecting bag; both ends of the open half-ring are hinged to both ends of the water retaining fence at an adjustable angle; the middle part of the open half-ring is connected with the other part of the opening edge of the water collecting bag.

[0006] Further, the water collecting bag is in a funnel shape, and a suction device connection port is arranged at the lower end of the water collecting bag.

[0007] Further, the lower end of the water collecting bag is inclined to one side.

[0008] Further, both the water retaining fence and the open half-ring are in a semi-circular shape, and the diameter of the open half-ring is larger than the diameter of the water retaining fence.

[0009] Further, it further comprises a connecting pin shaft. A first pin hole is arranged at the end of the water retaining fence, and a second pin hole is arranged on the open half-ring. The connecting pin shaft is inserted into the first pin hole and the second pin hole to enable the water retaining fence and the open half-ring to be hinged together. The outer wall of the water retaining fence and the inner side wall of the open half-ring are mutually attached and can be relatively fixed through friction.

[0010] Further, a limiting block is arranged at the end of the water retaining fence, and when the open half-ring is opened to the extreme position, it abuts against the open half-ring.

[0011] Further, a peelable release film is covered on the sticking surface.

[0012] Due to adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model is applicable to intervertebral foramen mirror surgery. The design advantage of the integral film body and water collecting bag greatly facilitates installation and use. At the same time, through the supportable and openable water inlet, the water inlet can be fixed, greatly reducing the overflow of the flushing liquid, keeping the patient's surgical drape, the patient's and doctor's clothes from being wet, keeping the ground dry, reducing the risk of surgical infection, improving the doctor's satisfaction and the patient's medical experience, and meeting the surgical requirements; solving the technical problems of the traditional intervertebral foramen mirror surgery film drainage device being separately arranged and difficult to install, and the opening of the water collecting bag being without support and easily deformed.

[0014] 2. After connecting the aspirator connecting tube to the aspirator through the provided aspirator connection port of the present utility model, the operation can be carried out. The flushing liquid will flow into the water collection bag at a lower place and then be sucked away by the aspirator, which can protect the patient's back from hypothermia caused by being soaked by the flushing liquid for a long time and reduce the occurrence of hypothermia in the patient. The lower end of the water collection bag is inclined to one side, occupying a small space and avoiding blocking the operation of the doctor taking intraoperative X-rays.

[0015] 3. The present utility model is provided with a water blocking fence and an opening half-ring that are opened and closed through a friction structure, with a simple structure, low cost, and convenient operation. By setting a limit block, it can prevent the water blocking fence and the opening half-ring from opening too large, resulting in a smaller opening of the water stop bag and poor water collection effect, thus improving reliability. In addition, the water blocking fence and the opening half-ring of the present utility model can be folded into small pieces, which is convenient for the entire film device to be folded into small pieces for storage, reducing the occupied space.
