Description

Technical Field

[0001] This utility model relates to the field of medical facility technology, and in particular to a medical surgical membrane. Background Technology

[0002] A surgical membrane is a medical device used during surgery to prevent surgical contamination and infection, and to collect surgical tissue specimens. It contains a filter that filters the surgical tissue specimen, allowing for the selection of desired tissue fluids for surgical analysis.

[0003] During surgery, it may be necessary to filter various tissue fluids, which requires changing different filters. However, the existing filters and surgical membranes are fixed together, so it is impossible to replace the filters separately; the entire surgical membrane must be replaced. This requires removing the old surgical membrane from the wound and then attaching the new one, which takes a long time and delays the surgery. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a medical surgical membrane to solve the problem that the filter in the surgical membrane cannot be replaced separately in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is a medical surgical membrane, comprising:

[0006] The surgical area is equipped with a window for performing surgery;

[0007] A collection tube is positioned below the surgical area;

[0008] The guide bag has a first connecting end and a second connecting end that are opposite to each other. The first connecting end is connected to the lower end of the surgical area, and the second connecting end is connected to the upper end of the collection tube. The width of the guide bag gradually decreases from the first connecting end toward the second connecting end.

[0009] A filter that is detachably connected to the guide bag or the collection tube.

[0010] Furthermore, the filter is provided with a suspension part, which can abut against the inner wall of the guide bag and suspend the filter in the collection tube.

[0011] Furthermore, the filter is cylindrical in shape, and a retaining ring is provided on the outer periphery of the filter to form the suspension portion.

[0012] Furthermore, the retaining ring is made of rubber.

[0013] Furthermore, the cross-sectional area of ​​the filter gradually decreases from top to bottom, and the cross-sectional area at the lower end of the filter is smaller than the cross-sectional area of ​​the collecting tube, while the cross-sectional area at the upper end of the filter is larger than the cross-sectional area of ​​the second connecting end.

[0014] Furthermore, the filter is cylindrical, the cross-sectional area of ​​the filter is larger than the cross-sectional area of ​​the collection tube, and the guide bag is elastic enough to hold the filter in place.

[0015] Furthermore, the surgical area has a first edge, a second edge, a third edge, and a fourth edge, the fourth edge being connected to the first connecting end, and a waterproof strip being provided on the first edge, the second edge, and the third edge, with the waterproof strip protruding from the surface of the surgical area.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] The filter is detachable. When different tissues need to be screened in the surgical specimen during surgery, only different filters need to be replaced to obtain different tissue fluids. There is no need to replace the entire surgical membrane, which greatly reduces the time required to replace the filter and will not delay the normal progress of the surgery.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] Please refer to Figures 1-2 This utility model discloses a medical surgical membrane, comprising:

[0027] Surgical area 100, wherein the surgical area 100 is provided with a window for performing surgery;

[0028] A collection tube 300 is disposed below the surgical area 100;

[0029] The guide bag 200 has a first connecting end and a second connecting end that are opposite to each other. The first connecting end is connected to the lower end of the surgical area 100, and the second connecting end is connected to the upper end of the collection tube 300. The width of the guide bag 200 gradually decreases from the first connecting end toward the second connecting end.

[0030] The filter 400 is detachably connected to the guide bag 200 or the collection tube 300.

[0031] Specifically, a window is opened in the surgical area 100 to facilitate the operation. The surgical tissue specimens generated during the operation flow through the guide bag 200 and are filtered by the filter 400 before flowing into the collection tube 300 to facilitate the collection of the surgical tissue specimens.

[0032] Importantly, the filter 400 in this application is detachable. When different tissues need to be screened in the surgical tissue specimen during surgery, only different filters 400 need to be replaced to obtain different tissue fluids. There is no need to replace the entire surgical membrane, which greatly reduces the time required to replace the filter 400 and will not delay the normal progress of the surgery.

[0033] Furthermore, the filter 400 is provided with a suspension part, which can abut against the inner wall of the guide bag 200 and suspend the filter 400 in the collection tube 300.

[0034] Specifically, a suspension part is provided at the top of the filter 400. The cross-sectional area of ​​the suspension part is larger than that of the second connecting end, so that the suspension part cannot pass through the second connecting end and fall into the collection tube 300, so that it can abut against the inner wall of the guide bag 200. The rest of the filter 400 extends into the collection tube 300, so that the entire filter 400 is suspended on the guide bag 200 by the suspension part.

[0035] Furthermore, the filter 400 is cylindrical, and a retaining ring 410 is provided on the outer periphery of the filter 400 to form the suspension portion.

[0036] Specifically, the filter 400 is cylindrical with equal cross-sectional areas at all heights. A retaining ring 410 is provided on the outer ring of the top of the filter 400. The area of ​​the retaining ring 410 is larger than the cross-sectional area of ​​the second connecting end, so that the retaining ring 410 can abut against the inner wall of the guide bag 200 to suspend the filter 400.

[0037] When the filter 400 needs to be replaced, simply lift the filter 400 upwards to remove it, and then insert the new filter 400 into the collection tube 300 along the guide bag 200 until the retaining ring 410 abuts against the inner wall of the collection bag.

[0038] Furthermore, the retaining ring 410 is made of rubber.

[0039] Since the retaining ring 410 is the only contact point between the entire filter 400 and the guide bag 200, the part of the guide bag 200 in contact with the retaining ring 410 is subjected to greater force and is easily torn by the retaining ring 410. Therefore, making the retaining ring 410 with a soft material such as rubber can effectively protect the guide bag 200 from being torn by the retaining ring 410.

[0040] Furthermore, the cross-sectional area of ​​the filter 400 gradually decreases from top to bottom, and the cross-sectional area of ​​the lower end of the filter 400 is smaller than the cross-sectional area of ​​the collection tube 300, while the cross-sectional area of ​​the upper end of the filter 400 is larger than the cross-sectional area of ​​the second connection end.

[0041] Specifically, the filter 400 is in the shape of an inverted frustum or a cone, with the smaller end extending into the collection tube 300 and the larger end abutting against the inner wall of the guide bag 200 to suspend the filter 400.

[0042] Furthermore, the filter 400 is cylindrical, the cross-sectional area of ​​the filter 400 is larger than the cross-sectional area of ​​the collection tube 300, and the guide bag 200 is elastic enough to hold the filter 400 in place.

[0043] Specifically, the collection tube 300 is made of plastic and has a certain degree of elasticity. The filter 400 can be inserted into the collection tube 300 and spread out the collection tube 300 so that it can be stuck in the collection tube 300 and will not fall down. It also enables the filter 400 to be detachably connected.

[0044] Furthermore, the surgical area 100 has a first edge, a second edge, a third edge and a fourth edge, the fourth edge being connected to the first connecting end, and a waterproof strip being provided on the first edge, the second edge and the third edge respectively, and the waterproof strip being provided protruding from the surface of the surgical area 100.

[0045] Waterproof strips are installed on the upper left, right and three sides of the surgical area 100 to waterproof the surgical area 100 and prevent surgical contamination.

[0046] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0047] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
