Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and in particular, relates to a perineal post and a traction system for hip arthroscopy surgery. Background Art

[0002] Hip arthroscopy is a minimally invasive surgical method used for hip joint diseases in recent years. Compared with open surgery, hip arthroscopy has the characteristics of less bleeding, shorter postoperative recovery time, fewer postoperative complications, less damage to the femoral head, and reduced risk of avascular necrosis.

[0003] With the development of hip arthroscopy, its indications now include primary pathological changes in the hip joint, peritrochanteric space disease, trauma, hip fracture, pediatric hip disease, and evaluation of pain after total joint replacement. For this reason, hip arthroscopy plays an increasingly important role in orthopedics, especially in the field of hip surgery.

[0004] The natural space of the hip joint is very narrow, so hip arthroscopy requires the use of a traction frame to axially pull the patient's affected limb to increase the hip joint space and provide sufficient working space for the introduction of arthroscopy and instruments. In addition, a perineal column needs to be placed under the patient's perineum area to provide support and maintain correct body posture.

[0005] However, during long-term traction, the perineal column continuously compresses the patient's perineal area and may even lead to complications caused by traction injuries to the femoral nerve, sciatic nerve and pudendal nerve. The main symptoms are numbness in the groin, inner and outer thighs, and dorsum of the foot.

[0006] It is understandable that traction has a significant effect on the numbness area. However, currently only the force applied by the traction frame can be controlled, and it is difficult to evaluate the pressure of the perineum column on the perineum area of ​​the patient. Utility Model Content

[0007] The present application provides a perineum post and a traction system for hip arthroscopy surgery, so as to solve the problem that it is difficult to assess the pressure acting on the perineum area of ​​the patient through the existing perineum post.

[0008] According to one aspect of the present application, a perineum column is provided, comprising a column body and a pressure detection component; the column body can undergo elastic deformation when subjected to force and is provided with a plurality of contact areas, the plurality of contact areas being arranged at intervals along the circumference of the column body on the outer peripheral wall of the column body; the pressure detection component is used to collect the applied force and is in plurality, and at least one pressure detection component is provided in each contact area.

[0009] In an optional solution of the present application, a single contact area is provided with at least one mounting protrusion, and the mounting protrusion protrudes from the outer peripheral wall of the column; the pressure detection component is attached to the mounting protrusion.

[0010] In an optional solution of the present application, when there are multiple mounting protrusions in a single contact area, the multiple mounting protrusions are arranged at intervals along the axial direction of the column.

[0011] In an optional solution of the present application, the cylinder is a frustum cylinder, and the diameter of the cylinder is first increased and then decreased along the axial direction of the cylinder.

[0012] In an optional solution of the present application, the diameter of the cylinder is 250 mm to 400 mm.

[0013] In an optional solution of the present application, the column is any one of an elastic silicone column, an elastic rubber column and an elastic plastic column.

[0014] In an optional solution of the present application, the pressure detection component is a flexible film pressure sensor.

[0015] In an optional solution of the present application, a protective cover is also included, which is externally mounted on the column and covers each pressure detection component in the contact area.

[0016] In an optional solution of the present application, a mounting hole is provided at one axial end of the column for connecting to the traction frame.

[0017] According to another aspect of the present application, a traction system for hip arthroscopy surgery is provided, including a traction frame, a display device, a pressure collection module and the above-mentioned perineum column; the traction frame is provided with a mounting column, and the perineum column is connected to the mounting column; the pressure collection module is connected to each pressure detection component for collecting pressure data, and the display device is connected to the pressure collection module for displaying the pressure data.

[0018] In summary, the perineal post and the traction system for hip arthroscopy provided by the present application have at least the following beneficial effects:

[0019] The perineal column at least comprises a column body and a pressure detection component, wherein the column body can be elastically deformed and the peripheral wall is formed with a plurality of contact areas arranged at intervals, and the contact areas can contact the perineal area of ​​the patient. The pressure detection component is located at the contact area, and when the patient is in a traction state, the pressure detection component is compressed.

[0020] The pressure detection component can convert the pressure into an electrical signal, and convert it into an electrical signal that can be recognized by the display device through the pressure acquisition module, and display the pressure data through the display device.

[0021] It can be seen that the perineal column provided by the present application in conjunction with the pressure collection module and the display device can evaluate the pressure applied by the perineal column to the perineum area of ​​the patient. In this way, the operator can adjust the traction frame according to the data displayed by the display device so that the traction force is within an appropriate range, thereby reducing the risk of complications caused by long-term high traction force.

If there is a description of "plurality", the general meaning is to include at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed" and so on should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection, it can be a direct connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they are contradictory.

[0038] Figure 1 This is a schematic diagram of a conventional traction system used in hip arthroscopy. Figure 1The existing traction system includes a traction frame 200 and a perineum column 10a. The traction frame 200 is used to provide a pulling force along the direction of the leg extension to the patient's legs to pull the hip joint apart. The perineum column 10a abuts against the perineum of the patient to ensure that the hip joint is in a suitable posture.

[0039] It is understandable that under the action of the traction frame 200, the perineal column 10a compresses the patient's perineum. During a long operation, the patient is under a large traction force for a long time, which may even cause complications due to traction injuries to the femoral nerve, sciatic nerve and pudendal nerve.

[0040] At present, the operator can only control the force applied by the traction frame. As can be seen from the above, the component acting on the perineum of the patient is the perineum column 10a, and it is difficult to evaluate the pressure of the existing perineum column 10a acting on the perineum of the patient.

[0041] To this end, the present application provides a traction system for hip arthroscopic surgery. Figure 2 This is a partial schematic diagram of a traction system for hip arthroscopy surgery provided according to one embodiment of the present application. It should be noted that: Figure 2 Only the mounting post 210 of the traction frame 200 is shown.

[0042] See also Figure 2 The traction system includes a perineum column 100, a traction frame 200, a display device 300, and a pressure collection module 400. The traction frame 200 is provided with a mounting column 210, and the perineum column 100 is connected to the mounting column 210.

[0043] Figure 3 for Figure 2 Schematic diagram of the perineal column 100 in another viewing angle. Figure 4 for Figure 2 Exploded view of the perineal post 100 in FIG. Figure 3 and Figure 4 The perineum post 100 includes a post body 110 and a pressure detection component 120 .

[0044] The column 110 can be elastically deformed when subjected to force and is provided with a plurality of contact areas S, which are arranged at intervals along the circumference of the column 110 on the outer peripheral wall of the column 110. The pressure detection components 120 are used to collect the applied force and are in multiple numbers, and at least one pressure detection component 120 is provided in each contact area S.

[0045] Furthermore, the pressure acquisition module 400 is connected to each pressure detection component 120 for collecting pressure data, and the display device 300 is connected to the pressure acquisition module 400 for displaying the pressure data.

[0046] In this embodiment, the perineum column 100 is composed of a column 110 and a pressure detection component 120, wherein the outer peripheral wall of the column 110 is formed with a plurality of contact areas S arranged at intervals along the circumferential direction. Here, the contact areas S can abut against the perineum area of ​​the patient. Multiple means that the number is not less than 2.

[0047] It should be understood that when the traction frame 200 pulls the patient's legs, the perineum column 100 will exert pressure on the patient's perineum area, and the perineum column 100 is in a stressed state. Accordingly, the column 110 can produce elastic deformation, and each contact area S of the column 110 abuts against the patient's perineum area.

[0048] It should be understood that when the pressure detection component 120 in the contact area S is in a stressed state, the pressure detection component 120 can convert the pressure into an electrical signal, and convert it into an electrical signal recognizable by the display device 300 via the pressure acquisition module 400, and display the pressure data via the display device 300.

[0049] It can be seen that the perineal column 100 provided by the present application, in conjunction with the pressure collection module 400 and the display device 300, can evaluate the pressure applied by the perineal column 100 to the perineum area of ​​the patient. In this way, the operator can adjust the traction frame 200 according to the data displayed by the display device 300, so that the traction force is within a suitable range, thereby reducing the risk of complications caused by long-term high traction force.

[0050] It should be noted that the pressure detection component 120 can convert pressure into an electrical signal. In a specific application, the pressure detection component 120 may be a pressure sensor.

[0051] The pressure acquisition module 400 has the functions of filtering, amplifying, converting electrical signals, etc. In a specific application, the pressure acquisition module 400 can be a circuit board with a filtering circuit, a signal amplifying circuit, a conversion circuit, etc., to filter, amplify, and convert the electrical signal transmitted by the pressure detection component 120 to debug it into a recognizable electrical signal.

[0052] The display device 300 can display pressure data according to the electrical signal sent by the pressure acquisition module 400. In a specific application, the display device 300 includes, for example, a digital pressure gauge, a liquid crystal display, and the like.

[0053] It should be noted that the perineal column 100 is generally clamped between the patient's legs and located at the base of the thigh. Figure 2In the embodiment shown, the number of contact areas S is 3, of which 2 contact areas S are arranged opposite to each other for contacting the bases of the two thighs, and the remaining contact area S is located between the two opposite contact areas S and is used to contact the perineum. It can be seen that the perineum area mainly refers to the perineum and the bases of the two thighs. Of course, the number of contact areas S is not limited to the embodiment shown in the figure, and can be adjusted according to needs.

[0054] In addition, Figure 2 In the illustrated embodiment, the cables between the pressure detection component 120 and the pressure acquisition module 400 are exposed outside the column 110. This is to facilitate understanding of the present solution. In specific applications, these cables can be arranged inside the column 110 to achieve the effect of hiding the cables.

[0055] In a further optional embodiment, a single contact area S is provided with at least one mounting protrusion 111 , and the mounting protrusion 111 protrudes from the outer peripheral wall of the column 110 . The pressure detection component 120 is attached to the mounting protrusion 111 .

[0056] In this embodiment, the mounting protrusion 111 protrudes from the outer peripheral wall of the column 110, so that when the contact area S contacts the perineum of the patient, it is ensured that the pressure detection component 120 located on the mounting protrusion 111 can be pressed, that is, it is ensured as much as possible that the pressure detection component 120 can detect pressure data. In addition, the number of the pressure detection component 120 and the mounting protrusion 111 are equal and both are even numbers.

[0057] In a further optional embodiment, when there are multiple mounting protrusions 111 in a single contact area S, the multiple mounting protrusions 111 are spaced apart along the axial direction of the column 110 .

[0058] In this embodiment, the contact area S on one side has a plurality of mounting protrusions 111 arranged at intervals along the axial direction of the column 110 . Accordingly, the pressure sensing components 120 in a single contact area S are also arranged at intervals along the axial direction of the column 110 .

[0059] In this way, it is ensured as much as possible that at least one pressure detection component 120 in a single contact area S is completely located between the column 110 and the patient's skin, so as to ensure that relatively accurate data can be collected.

[0060] In the illustrated embodiment, a single contact area S is provided with three pressure detection components 120, and the three pressure detection components 120 are arranged at intervals along the axial direction of the column 110. In a specific application, the display device 300 can display the pressure data acquired by each pressure detection component 120, and the operator can use the maximum pressure value collected in a single contact area S displayed by the display device 300 as an evaluation reference.

[0061] In some optional embodiments, the column 110 is a frustoconical column, and the diameter of the column 110 increases first and then decreases along the axial direction of the column 110 .

[0062] In this embodiment, the column 110 is a truncated cone column, so that the outer peripheral wall of the column 110 is smoothly transitioned. The diameter of the column 110 is gradually set, and the diameters of the two axial ends of the column 110 are relatively small, and the diameter of the middle position is relatively large.

[0063] In the illustrated embodiment, the diameter transition area of ​​the column 110 is located in the middle and upper part, and the diameter transition area refers to the area with the largest diameter. The contact area S is located below the diameter transition area, so that the upper and lower positions of the thigh root of the patient can be limited. The axial ends of the column 110 are set relatively thin, so that it is easy to observe whether the contact position is appropriate.

[0064] It should be understood that the diameter of the column 110 is one of the key factors affecting the contact area. If it is too large, it may exceed the range of motion of the hip joint, and if it is too small, it may lead to insufficient contact area. If the contact area is too small, it will lead to excessive pressure, which will also have adverse effects on the patient. Specifically, the diameter of the column 110 is 250 mm to 400 mm.

[0065] Figure 5 FIG. 1 is an exploded view of a perineal post 100 provided according to another embodiment of the present application. Figure 5 The perineum column 100 includes a protective cover 130 , which is sleeved on the column body 110 and covers each pressure detection component 120 in the contact area S.

[0066] In this embodiment, the column 110 and the pressure detection components 120 in the contact area S are covered by the protective cover 130 to protect the column 110 and the pressure detection components 120 , thereby extending the service life of the perineum column 100 .

[0067] In a specific application, the protective cover 130 is a consumable material, which can be generally composed of medical dressings, including gauze, cotton wool, etc., and is replaced after each operation.

[0068] As can be seen from the foregoing, the column 110 will undergo elastic deformation when subjected to force, and after the traction state is released, the column 110 can be reset to continue to be used in the next operation. In a specific application, the column 110 is made of an elastic material. In this embodiment, the column 110 is any one of an elastic silicone column, an elastic rubber column, and an elastic plastic column, which can be selected according to needs.

[0069] In addition, when the cylinder 110 is a truncated cone cylinder, the outer peripheral wall of the cylinder 110 is an arc surface, and accordingly, the outer peripheral wall of the mounting protrusion 111 is also formed as an arc surface. In an optional embodiment, the pressure detection component 120 is a flexible film pressure sensor, so that the mounting protrusion 111 is fitted, ensuring the matching area between the pressure detection component 120 and the mounting protrusion 111.

[0070] See also Figure 4 In some optional embodiments, a mounting hole H is provided at one axial end of the column 110 for connecting with the traction frame 200 .

[0071] In this embodiment, the column 110 is provided with a mounting hole H, so the column 110 is a hollow column, and the mounting hole H is used to match the mounting post 210. Since the column 110 is made of elastic material, the mounting hole H and the mounting post 210 can achieve interference fit to fix the perineum post 100 on the traction frame 200.

[0072] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
