Technical Field

[0001] The invention relates to the technical field of medical appliances, and in particular to an easy-to-use distraction device for surgical treatment of hernia. Background Art

[0002] Inguinal hernia refers to the mass formed when the abdominal wall muscles and fascia are weakened and / or the intra-abdominal pressure is increased, and the abdominal organs protrude through the defect in the groin area to the body surface. It is commonly known as "hernia". Inguinal hernia cannot heal on its own, and may become incarcerated, causing severe local pain, or even intestinal necrosis, which is life-threatening. Therefore, once an inguinal hernia is diagnosed, repair surgery should be performed as soon as possible.

[0003] During surgical treatment, an oblique incision is made in the groin area, and the skin, subcutaneous tissue and external oblique aponeurosis are cut in sequence. Then the incision needs to be stretched open to facilitate the surgical operation. Generally, the incision is stretched open by clamps or auxiliary stretching devices. However, both clamps and existing stretching devices are troublesome to use.

[0004] Among them, the existing expansion device uses a component with an elastic device to flexibly control the size of the incision. However, when the incision is expanded to a required size, it is necessary to further use some fixing devices to fix the expansion device to the required size or a special person needs to control it within a fixed size range by hand. This is extremely inconvenient and sometimes even requires a second person to assist in fixing. Summary of the invention

[0005] In order to overcome the problem that when the incision is stretched to a required size, some fixing devices need to be further used to fix the stretching device at the required size or a special person needs to manually control it within a fixed size range, which is extremely inconvenient and sometimes even requires a second person to assist in the fixation. The technical problem to be solved by the present invention is to provide a stretching device for hernia surgical treatment that can extremely conveniently fix the incision size at a certain position.

[0006] In order to solve the above technical problems, the present invention provides an easy-to-use distraction device for surgical treatment of hernia, including a connecting plate, the connecting plate is provided with a slide groove, the connecting plate is provided with a socket close to the slide groove, the slide groove is provided with a slider, the slider is provided with a magnet and a first spring, the first spring is sleeved with an iron block, and the iron block matches the socket.

[0007] Preferably, the first spring is fixed in the slider at one end away from the magnet.

[0008] Preferably, the slider is fixedly connected to the two ends of the top of the first connecting rod, the first connecting rod and the connecting plate are perpendicular to each other, there are two first connecting rods and two connecting plates, the two first connecting rods are parallel to each other, and the two connecting plates are parallel to each other.

[0009] Preferably, a connecting block is fixedly installed at the middle portion of the first connecting rod, and the connecting block is fixedly connected to a supporting plate.

[0010] Preferably, both ends of the first connecting rod are fixedly connected to a second connecting rod respectively.

[0011] Preferably, a second spring is fixedly installed between opposite surfaces of two second connecting rods located on the same side of the first connecting rod.

[0012] Preferably, a handle is fixedly mounted on one end of the second connecting rod away from the first connecting rod, and a rubber pad is sleeved on the outer surface of the handle.

[0015] Preferably, an anti-slip pad is provided on the surface of the support plate, and the support plate is arc-shaped.

[0016] Beneficial Effects The present invention forms an elastic force on the iron block through the first spring inside the slider, which can clamp the iron block in the jack inside the slide groove and limit the position of the slider. The limit of the expansion device is achieved by limiting the position of the slider. When the magnet is energized to generate a magnetic field, the iron block is sucked into the slider, and the slider can slide in the slide groove, thereby adjusting the size of the expansion device. When the slider needs to be fixed again, the magnet can be powered off, thereby overcoming the problem that when the incision is expanded to the required size, it is necessary to further use some fixing devices to fix the expansion device specifically to the required size or a special person needs to manually control it within a fixed size range, which is extremely inconvenient and sometimes even requires a second person to assist in the fixing.

[0017] The second spring of the present invention is installed on the second connecting rod, which is convenient and labor-saving during manual operation. The handle is provided with a rubber pad to prevent the hands from sweating and slipping.

[0018] The support plate of the present invention is provided with an anti-skid pad to increase the stability between the support plate and the incision.

DETAILED DESCRIPTION

[0022] In order to further understand the content of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0023] Example 1 A convenient hernia surgical treatment distraction device, such as Figure 1-5 As shown, it includes a connecting plate 12, the connecting plate 12 is provided with a slide groove 121, the connecting plate 12 is provided with a socket 122 close to the slide groove 121, the slide groove 121 is provided with a slider 15, the slider 15 is provided with a magnet 151 and a first spring 152, the first spring 152 is sleeved with an iron block 153, and the iron block 153 is consistent with the socket 122.

[0024] The first spring 152 is fixed in the slider 15 at one end away from the magnet 151 .

[0025] The slider 15 is fixedly connected to the two ends of the top of the first connecting rod 1. The first connecting rod 1 and the connecting plate 12 are perpendicular to each other. There are two first connecting rods 1 and two connecting plates 12. The two first connecting rods 1 are parallel to each other, and the two connecting plates 12 are parallel to each other.

[0026] Exemplarily, the two first connecting rods 1 can slide on the connecting plate 12 via the sliding blocks 15 .

[0027] Specifically, the insertion holes 122 disposed inside the two connecting plates 12 are mirror images of each other, thereby ensuring the stability of the entire spreading device during operation.

[0028] A connecting block 14 is fixedly mounted at the middle of the first connecting rod 1 , and the connecting block 14 is fixedly connected to the supporting plate 2 .

[0029] Exemplarily, the support plate 2 opens the incision under the action of the first connecting rod 1 .

[0030] The two ends of the first connecting rod 1 are respectively fixedly connected with the second connecting rod 11 .

[0031] A second spring 13 is fixedly installed between opposite surfaces of the two second connecting rods 11 located on the same side of the first connecting rod 1 .

[0032] Exemplarily, the elastic range of the second spring 13 is adapted to the length of the slide slot 121 .

[0033] A handle 3 is fixedly mounted on one end of the second connecting rod 11 away from the first connecting rod 1 , and a rubber pad is sleeved on the outer surface of the handle 3 .

[0034] The second connecting rod 11 is equipped with a control switch 4 , and the control switch 4 is electrically connected to the magnet 151 .

[0035] Exemplarily, the magnets 151 are powered by nearby electricity or by installing a battery, and one control switch 4 controls the power on and off of the four magnets 151 . The control switch 4 is installed at one end of the second connecting rod 11 close to the handle 3 .

[0036] A third connecting rod 141 is fixedly connected to the bottom of the connecting block 14 . The third connecting rod 141 is L-shaped. The support plate 2 is fixedly connected to one end of the third connecting rod 141 away from the connecting block 14 .

[0037] An anti-slip pad 21 is provided on the surface of the support plate 2, and the support plate 2 is arc-shaped.

[0038] Working principle: When in use, the medical staff first turns on the control switch 4, and the magnets 151 inside the four sliders 15 are energized to generate a magnetic field. The magnetic field generated by the magnets 151 will generate an attraction to the iron block 153 inside the slider 15, and the iron block 153 will be sucked out of the jack 122. At this time, the medical staff will use both hands to squeeze the two second connecting rods 11 at both ends at the same time. Driven by the slider 15, the distance between the two second connecting rods 11 on the same side can be shortened, and then the distance between the two first connecting rods 1 can be shortened. When the distance between the two first connecting rods 1 is shortened, the distance between the two support plates 2 will also be shortened under the drive of the third connecting rod 141. At this time, the two support plates 2 can be placed on the inner side of the incision, and then the medical staff can The medical staff slowly releases their hands, and the restoring force of the second spring 13 causes the two second connecting rods 11 to slide in the opposite direction, and at the same time, the first connecting rod 1 is also driven to slide in the opposite direction. When the incision is stretched to the required size, the medical staff immediately turns off the control switch 4, and the magnet 151 inside the slider 15 is powered off, and the magnetic field generated by the magnet 151 disappears. Under the action of the restoring force of the first spring 152, part of the length of the iron block 153 is bounced into the socket 122 set inside the connecting plate 12. At this time, the four sliders 15 stop sliding under the action of the iron block 153, so that the two first connecting rods 1 also stop moving. At the same time, the two second connecting rods 11 at both ends will also stop moving, and the second spring 13 will also stop the restoring force. At this time, the distance between the two support plates 2 is fixed, that is, the size of the incision is fixed.

[0039] When the size of the expanded incision needs to be adjusted, when the expanded distance of the incision needs to be reduced, the medical staff turns on the control switch 4, the slider 15 can slide, and the medical staff will squeeze the two second connecting rods 11 at both ends with both hands at the same time, so that when the incision is adjusted to the required size, the medical staff immediately turns off the control switch 4, and the distance between the two support plates 2 is fixed, that is, the expanded incision size is fixed; When the incision needs to be expanded, the medical staff turns on the control switch 4, and the slider 15 can slide. Through the restoring force of the second spring 13, the two second connecting rods 11 slide in the opposite direction, and at the same time, the first connecting rod 1 also slides in the opposite direction. When the incision is expanded to the required size, the medical staff immediately turns off the control switch 4, and the distance between the two support plates 2 is fixed, that is, the size of the expanded incision is fixed.

[0040] Through the above operation, when adjusting the incision size, medical staff no longer need to use some fixing devices, such as fixing bolts or limit blocks, to fix the expansion device at the required size and position. There is no need for a dedicated person to deliberately control the expansion device at a fixed size and position by hand, and there is no need for a second person to assist in the fixation. This will bring great convenience to the relevant medical staff.

[0041] Furthermore, the length of the iron block 153 is greater than that of the insertion hole 122 , ensuring that the iron block 153 can clamp the slider 15 while being inserted into the insertion hole 122 , and the first spring 152 has sufficient restoring force to clamp the iron block 153 into the insertion hole 122 .

[0042] Furthermore, the positions of the insertion holes 122 provided in the connecting plates 12 on both sides are mirror images of each other in order to ensure that the entire expansion device has a relative stability whether it is released or contracted.

[0043] Furthermore, a control switch 4 is provided to control the on and off of power to the four magnets 151, so as to ensure the consistency of the movement state of the entire device. The control switch 4 is installed at one end of the second connecting rod 11 close to the handle 3, which is convenient for medical staff to operate. It is preferably installed on the right side, that is, the side of the usual dominant hand. The magnets 151 are powered by nearby electricity or by installing a battery, so that the entire device is convenient to power.

[0044] Furthermore, a rubber pad is provided on the outer surface of the handle 3 to prevent the palms of medical personnel from sweating and slipping during operation, so as to avoid causing unnecessary impact on the patient.

[0045] Furthermore, the anti-skid pad 21 is provided on the surface of the support plate 2 to increase the stability between the support plate and the incision. The support plate 2 is set to be arc-shaped, which is intended to reduce the contact area between the support plate and the incision without affecting the supporting strength of the support plate.
