Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a self-adaptive compression dressing device for circumcision surgery. BACKGROUND

[0002] In addition to the therapeutic significance, circumcision is a surgery that can be implemented with the willingness of all men. With the popularization of the concept of health and the love for partners, the acceptance of circumcision will be higher and higher. Circumcision can reduce the incidence of infection, help puberty development, reduce the incidence of tumors and improve function.

[0003] The current postoperative compression method for circumcision is elastic bandage compression. When using the elastic bandage, it needs to be cut according to the part, and then the bandage is wrapped around the required part in multiple turns. The above process takes a lot of time and has the risk of increasing bleeding. The pressure of the elastic bandage is not easy to control, and if the compression is too loose, it cannot effectively stop bleeding, and if the compression is too tight, it may cause ischemic necrosis.

[0004] In terms of practicality, the postoperative compression with elastic bandage needs to be observed for a long enough time to determine whether the compression is too tight, but even if the compression pressure is appropriate during postoperative observation, there is still a risk of excessive pressure due to swelling after discharge at home.

[0005] In addition, the removal process of the elastic bandage is easy to cause pain, and children patients are extremely uncooperative due to pain, which brings difficulties to parents to remove the bandage at home and easily causes anxiety to parents. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a self-adaptive compression dressing device for circumcision surgery, which is controllable in pressure and easy to remove.

[0007] In order to solve the above technical problems, the application discloses a self-adaptive compression dressing device for circumcision operation. The device comprises an elastic clamp, a shell, a movable clamping jaw, an adjusting spring and a movable clamping jaw position adjusting mechanism. One side of the elastic clamp is provided with a notch. The shell comprises a top wall and a cavity, and the top wall is arranged below the notch end of the elastic clamp. The movable clamping jaw is slidably arranged in the cavity, the connecting end of the movable clamping jaw extending out of the top wall is detachably connected with one side of the notch in the elastic clamp, and the other side of the notch in the elastic clamp is detachably connected with the top wall. The movable clamping jaw position adjusting mechanism is installed in the cavity and connected with the movable clamping jaw through the adjusting spring, and is used for driving the movable clamping jaw to adjust the position, so that the elastic clamp wraps and clamps the circumcision part. The adjusting spring can adjust the extension and contraction amount according to the pressure change of the circumcision part on the movable clamping jaw, so as to change the wrapping and clamping force of the elastic clamp on the circumcision part.

[0008] The application adjusts the position of the movable clamping jaw, and then adjusts the size of the notch, so that the elastic clamp tightly holds the circumcision part and provides appropriate wrapping and clamping force. The adjusting spring is arranged between the movable clamping jaw and the movable clamping jaw position adjusting mechanism, and the adjusting spring can adjust the extension and contraction amount according to the pressure change of the circumcision part on the movable clamping jaw, so as to change the wrapping and clamping force of the elastic clamp on the circumcision part.

[0009] Taking the adjusting spring as a compression spring, when the circumcision part swells, the swollen circumcision part drives the elastic clamp to expand, the elastic clamp drives the movable clamping jaw to displace, and the adjusting spring is further compressed, so as to adjust the pressure of the elastic clamp on the circumcision part and protect the swelling area. When the swelling of the circumcision part subsides, the internal pressure of the elastic clamp decreases, the pressure of the movable clamping jaw on the adjusting spring decreases, the adjusting spring gradually releases and resets, and the corresponding dressing pressure can still be provided. Thus, the self-adaptive compression dressing process is realized.

[0010] The adjusting spring can also be a stretching spring, and the self-adaptive adjusting process is similar to that of the compression spring, so it will not be described again.

[0011] Further, the device further comprises a reset spring, the reset spring is located in the cavity, one end of the reset spring is connected with the shell, and the other end of the reset spring is connected with the movable clamping jaw. The reset spring is used for applying a force to the movable clamping jaw in the direction opposite to the force applied by the adjusting spring to the movable clamping jaw.

[0012] The device of the embodiment can improve the stability of the movable clamping jaw during movement by arranging the reset spring.

[0014] The device of the embodiment also has a one-step removal function. When the bandaging device is removed, the movable clamping jaw is driven to move to a position where the connecting end of the movable clamping jaw extending out of the top wall can be separated from the elastic clamping hoop, and then the elastic clamping hoop can be removed. At this time, the adjusting spring and the reset spring are both released, and the elastic clamping hoop is automatically expanded to a free state. The above removal process does not cause pain, avoids discomfort of the patient caused by pain during removal, and is convenient for parents to operate.

[0015] Specifically, the adjusting spring is a compression spring, one end of the adjusting spring abuts against the movable clamping jaw, and the other end of the adjusting spring abuts against the movable clamping jaw position adjusting mechanism. The reset spring is a compression spring, and the reset spring is located on the side of the movable clamping jaw away from the adjusting spring.

[0016] Specifically, the device includes a first protruding clamping jaw, a second protruding clamping jaw, and a fixed clamping jaw. The first protruding clamping jaw and the second protruding clamping jaw are respectively located on both sides of the notch and are fixedly connected with the elastic clamping hoop. One side of the notch in the elastic clamping hoop is connected with the connecting end of the movable clamping jaw extending out of the top wall through the second protruding clamping jaw in a detachable manner. The other side of the notch in the elastic clamping hoop is connected with the top wall through the first protruding clamping jaw and the fixed clamping jaw in a detachable manner.

[0017] Specifically, the movable clamping jaw position adjusting mechanism includes a movable sliding block and a pushing rod. The movable sliding block is slidably arranged in the cavity. One end of the pushing rod is located outside the shell for hand screwing, and the other end of the pushing rod extends into the cavity and is connected with the adjusting spring through the movable sliding block. When the pushing rod is screwed, the pushing rod can rotate and move forward or backward relative to the shell in the axial direction, thereby realizing the functions of driving the movable clamping jaw to adjust the position and adjusting the extension amount of the adjusting spring.

[0018] Specifically, the shell includes a shell body, an opening, a sealing plate, and a threaded hole. The opening is located on the side wall of the shell body close to the movable sliding block. The sealing plate is arranged at the opening for closing the opening. The threaded hole is arranged in the middle of the sealing plate. The other end of the pushing rod extends into the cavity through the threaded hole. The pushing rod is threadedly connected with the threaded hole.

[0019] Specifically, a long strip-shaped through slot is arranged at the corresponding position of the top wall and the movable clamping jaw and communicates with the cavity. One end of the movable clamping jaw extends out of the top wall from the long strip-shaped through slot.

[0020] Specifically, the cross section of the elastic clamping hoop is circular. When the elastic clamping hoop is in a free state, the notch is expanded to the maximum.

The movable clamping jaw is provided with a third circular hole on the side opposite to the reset spring, and one end of the reset spring close to the movable clamping jaw is clamped in the third circular hole.

[0022] Optionally, the elastic clamping hoop is made of rubber or nylon material.

[0023] Specifically, the sealing plate is connected with the shell through screws.

[0024] Beneficial effects:

[0025] (1) The position of the movable clamping jaw is adjusted, and then the size of the gap is adjusted, so that the elastic clamping hoop tightly holds the prepuce circumcision part and provides appropriate wrapping clamping force. The adjusting spring is arranged between the movable clamping jaw and the movable clamping jaw position adjusting mechanism, the adjusting spring can adjust the extension and contraction amount according to the pressure change of the prepuce circumcision part on the movable clamping jaw, so that the wrapping clamping force of the elastic clamping hoop on the prepuce circumcision part is changed. Taking the adjusting spring as a compression spring, when the prepuce circumcision part swells, the swollen prepuce circumcision part drives the elastic clamping hoop to expand, the elastic clamping hoop drives the movable clamping jaw to displace, and the adjusting spring is further compressed, so as to adjust the pressure of the elastic clamping hoop on the prepuce circumcision part, and protect the swelling area. When the prepuce circumcision part swells, the internal pressure of the elastic clamping hoop decreases, the pressure of the movable clamping jaw on the adjusting spring decreases, and the adjusting spring gradually releases the reset, and can still provide corresponding bandaging pressure. Therefore, the self-adaptive pressure bandaging process is realized. The adjusting spring can also be a stretching spring, and the self-adaptive adjusting process is similar to the compression spring, so it is not repeated. The self-adaptive pressure bandaging process realizes controllable pressure, can effectively stop bleeding, avoids the problem of ischemic necrosis caused by excessive wrapping clamping force in the elastic bandage mode in the prior art, and can ensure safety.

[0026] (2) In the present application, the position of the movable clamping jaw can be adjusted within a certain range, which fully meets the individual needs of different prepuce circumcision parts to the device.

[0027] (3) In one embodiment of the present invention, the device is provided with a reset spring, which can improve the stability of the movable claw during its movement. Furthermore, by setting the stroke of the reset spring, the connection end of the movable claw extending from the top wall is allowed to disengage from one side of the notch in the elastic clamp, so that the device of this embodiment also has a one-step removal function. When removing the bandaging device, the movable claw is driven by the movable claw position adjustment mechanism to move to a position where the connection end of the movable claw extending from the top wall can be disengaged from the elastic clamp, and the elastic clamp can be removed. At this time, the adjustment spring and the reset spring are both released, and the elastic clamp automatically expands to a free state. The above-mentioned removal process does not cause pain, avoids discomfort to the child caused by the pain of removal, and is convenient for parents to operate.

[0028] (4) In one embodiment of the present invention, the movable claw position adjustment mechanism includes a movable slider and a push rod. The movable slider is slidably arranged in the cavity; one end of the push rod is located outside the shell for manual tightening, and the other end extends into the cavity and is connected to the adjustment spring through the movable slider; when the push rod is screwed, the push rod can rotate forward or backward relative to the shell in the axial direction, thereby achieving the function of driving the movable claw to adjust the position and adjusting the expansion and contraction amount of the adjustment spring. Compared with the elastic bandage in the prior art, the manual tightening operation method of the movable claw position adjustment mechanism is more convenient for operators such as doctors and patients' families to operate. After surgery, the movable claw position adjustment mechanism can also be conveniently operated manually in a home environment to adjust the bandaging pressure to avoid excessive or insufficient pressure.

[0060] Example 1

[0061] like Figures 1 to 5 As shown, the embodiment provides an adaptive pressure bandage device for circumcision surgery, including an elastic clamp 100 and a pressure-adaptive clamping device. The pressure-adaptive clamping device includes a housing 900, a fixed clamping device 200, a movable clamping device 300, a movable slider 400, a sealing plate 500, an adjustment spring 700, a return spring 600, and a push rod 800.

[0062] In this embodiment, the movable slider 400 and the propulsion rod 800 constitute a movable claw position adjustment mechanism.

[0063] like Figure 2As shown, the elastic clamping hoop 100 in the embodiment is made of elastic resin material such as rubber and nylon material. The cross section of the elastic clamping hoop 100 is circular with a notch on one side. The size of the notch can be adjusted to adjust the inner diameter of the elastic clamping hoop 100 to adapt to different sizes of the wrapped part. In the free state, the notch of the elastic clamping hoop 100 is opened to the maximum. During the wrapping, the elastic clamping hoop 100 is sleeved on the outside of the penis of the child after the circumcision surgery. When the distance between the two sides of the notch becomes smaller, the elastic clamping hoop 100 shrinks inward and tightly holds the outside of the penis of the child, thereby generating local pressure and achieving pressure wrapping.

[0064] As shown in Figure 6 , the two sides of the notch are respectively provided with a first protruding clamping jaw 102 and a second protruding clamping jaw 103 for connecting the elastic clamping hoop 100 and the pressure self-adaptive clamping device together. Figure 6 As shown in , the first protruding clamping jaw 102 and the second protruding clamping jaw 103 are integrally formed with the elastic clamping hoop 100.

[0065] As shown in Figures 1 to 5 , the housing 900 of the pressure self-adaptive clamping device in the embodiment is in the shape of a rectangular plate, and the inside of the housing 900 forms a cavity 902. The fixed clamping jaw 200 is fixedly connected to the top wall 901 of the housing 900 and is used to be detachably connected with the first protruding clamping jaw 102 of the elastic clamping hoop 100. The movable clamping jaw 300 is slidably arranged in the cavity 902 of the housing 900. As shown in Figure 1 , the top wall 901 of the housing 900 and the movable clamping jaw 300 are provided with a long strip-shaped through slot 904 corresponding to the position of the cavity 902, and one end of the movable clamping jaw 300 extends out of the top wall 901 of the housing 900 through the long strip-shaped through slot 904 and is used to be detachably connected with the second protruding clamping jaw 103 of the elastic clamping hoop 100. The position of the movable clamping jaw 300 is adjusted to adjust the tightening degree of the elastic clamping hoop 100, and the tightening degree of the elastic clamping hoop 100 determines the size of the wrapping clamping force.

[0066] As shown in Figure 1 and Figure 2 , the end of the movable clamping jaw 300 extending out of the top wall 901 of the housing 900 through the long strip-shaped through slot 904 and the second protruding clamping jaw 103 of the elastic clamping hoop 100 and the fixed clamping jaw 200 and the first protruding clamping jaw 102 of the elastic clamping hoop 100 are all in sliding fit to facilitate detachment.

[0068] As shown in Figure 4 , the adjusting spring 700 is located between the movable jaw 300 and the movable slider 400 and is a compression spring. In the working state, one end of the adjusting spring 700 abuts against the movable jaw 300, and the other end abuts against the movable slider 400. The adjusting spring 700 is used to stably push the movable jaw 300 under the driving of the movable slider 400 and to provide a certain displacement space for the movable jaw 300 in the pressure self-adapting process. The pressure self-adapting process will be described later in relation to the use method. Further, as shown in Figure 7 , the side of the movable jaw 300 opposite to the movable slider 400 is provided with a first circular hole 301, and the movable slider 400 is provided with a second circular hole corresponding to the first circular hole. One end of the adjusting spring 700 is clamped in the first circular hole 301, and the other end is clamped in the second circular hole. By clamping the two ends of the adjusting spring 700 in the first circular hole and the second circular hole respectively, the inclination of the adjusting spring 700 in the pushing process is prevented.

[0069] As shown in Figure 4 , the reset spring 600 is a compression spring and is located in the cavity 902. The reset spring 600 is located on the side of the movable jaw 300 away from the adjusting spring 700. One end of the reset spring 600 abuts against the housing 900, and the other end abuts against the movable jaw 300, which is used to push back the movable jaw 300. Further, the side of the movable jaw 300 opposite to the reset spring 600 is provided with a third circular hole, and the end of the reset spring 600 close to the movable jaw 300 is clamped in the third circular hole.

[0070] As shown in Figure 1 and Figure 5 , one end of the pushing rod 800 is located outside the housing 900 for hand screwing, and the other end extends into the cavity 902 and abuts against the side of the movable slider 400 away from the adjusting spring 700. When the pushing rod 800 is screwed, the pushing rod 800 can rotate and move forward or backward in the axial direction relative to the housing 900, thereby realizing the function of driving the movable jaw 300 to adjust the position and adjusting the extension amount of the adjusting spring 700.

[0071] As shown in Figure 5 , the housing 900 includes a housing body, an opening 903, a sealing plate 500, and a threaded hole 501. The opening 903 is located on the side wall of the housing body close to the movable slider 400. The sealing plate 500 is arranged at the opening 903 to close the opening 903. The threaded hole 501 is arranged in the middle of the sealing plate 500, and the other end of the pushing rod 800 extends into the cavity 902 from the threaded hole 501. The pushing rod 800 is threadedly connected with the threaded hole 501, so that the pushing rod 800 can rotate and move forward or backward in the axial direction relative to the housing 900.

[0072] Figure 8Figure 1 shows a photograph of a self-adapting compression dressing device for circumcision surgery according to an embodiment of the present application. Figure 9 Figure 2 shows a photograph of a device according to an embodiment of the present application. Figure 10 Figure 3 shows a photograph of a device according to an embodiment of the present application after the elastic clamp is removed.

[0073] The use of a self-adapting compression dressing device for circumcision surgery according to an embodiment of the present application is as follows:

[0074] Before use, the elastic clamp 100 in the self-adapting compression dressing device is separated from the pressure-adapting clamp device.

[0075] During surgery, the gap 101 of the elastic clamp 100 is manually widened, and the circumcision site is set into the elastic clamp 100 through the gap 101. The two sides of the gap 101 of the elastic clamp 100 are respectively connected to the housing 900 of the pressure-adapting clamp device through the first protruding clamp 102 and the second protruding clamp 103. Then the advancing rod 800 is manually screwed, the advancing rod 800 rotates and moves forward, the advancing rod 800 drives the movable sliding block 400 to move, and the movable sliding block 400 drives the movable clamp 300 to move, thereby adjusting the degree of tightening of the elastic clamp 100 to adapt to the circumcision site of the child, so that the elastic clamp tightly holds the circumcision site and provides appropriate wrapping and clamping force.

[0076] When the circumcision site swells, the swollen circumcision site drives the elastic clamp 100 to widen, the movable clamp 300 moves away from the fixed clamp 200, the adjusting spring 700 is further compressed, and the return spring 600 is partially released. Under the action of the adjusting spring 700, the movable clamp 300 has a certain contraction space, thereby adjusting the pressure applied by the elastic clamp 100 to the circumcision site and protecting the swollen area. When the swelling of the circumcision site subsides, the internal pressure of the elastic clamp 100 decreases, the pressure of the movable clamp 300 on the adjusting spring 700 decreases, the adjusting spring 700 gradually releases the reset, the return spring 600 is compressed, and the corresponding wrapping and clamping force can still be provided. Thus, the self-adapting compression dressing process is realized.

[0077] When the bandaging device is removed, the embodiment has the feature of one-step removal. When the bandaging device is removed, the push rod 800 rotates and moves back a certain distance, the adjusting spring 700 and the reset spring 600 are released, the elastic clamp 100 is expanded to a free state, the movable clamping jaw 300 moves towards the direction close to the push rod 800 to a position allowing the connecting end of the movable clamping jaw 300 to extend out of the top wall 901 to be separated from the second protruding clamping jaw 103 in the elastic clamp 100, and then the elastic clamp 100 can be removed. Then manually expand the elastic clamp, and make the circumcision site pass through the gap 101 and exit the elastic clamp 100. The above removal process does not cause pain, avoids the discomfort of the patient caused by the removal pain, and is convenient for parents to operate.

[0078] The application provides a thought and method of a self-adaptive pressure bandaging device for a circumcision operation. There are many methods and approaches to realize the technical scheme, and the above description is only the preferred embodiment of the application. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the application, and these improvements and refinements should also be regarded as the protection scope of the application. The components not explicitly described in the embodiment can be realized by the existing technology.
