Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a retractor for a minimally invasive surgical channel for hypertensive cerebral hemorrhage. Background Art

[0002] Hypertensive cerebral hemorrhage is the most serious complication of hypertension. There are hundreds of thousands of patients with hypertensive cerebral hemorrhage in my country every year. If it is not treated in time after the onset of the disease, it will cause high mortality and disability rates, and cause serious economic and social burdens to families and society.

[0003] According to application number 202222390726.3, a minimally invasive surgical channel retractor for hypertensive cerebral hemorrhage discloses a stabilizing plate, a left plate and a right plate. The front of the stabilizing plate is movably connected to the left plate, the right side of the left plate is movably connected to the right plate, the middle part of the left plate is movably connected to a nut, the right side of the left plate is fixedly connected to an arc plate, the middle part of the arc plate has an empty groove, the top of the arc plate is movably connected to a movable block, and the interior of the stabilizing plate is fixedly connected with a transverse groove. The setting of the retraction head improves the humanized design, ensuring that the patient's wound is protected during use while achieving a convenient effect. The setting of the adjustment mechanism improves the efficiency of use, saves time and effort during use, and brings certain convenience to medical staff. The setting of the fixing mechanism improves the functionality between the structures, maximizes the mutual coordination between the structures, and achieves the effects of stability and movement.

[0004] In the above technical solution, the positions of the left and right plates need to be stabilized by frequently adjusting the nuts. The adjustment process is relatively cumbersome, which reduces the operating efficiency of medical staff. Utility Model Content

[0005] The purpose of the utility model is to provide a minimally invasive surgical channel retractor for hypertensive cerebral hemorrhage, so as to solve the problem of adjustment operation efficiency in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A minimally invasive surgical channel retractor for hypertensive cerebral hemorrhage comprises a left arm and a right arm, each of which is provided with a clamping arm, one end of which is provided with a hook, one side of the left arm is provided with an arc-shaped plate with a plurality of incisions formed on the surface of the arc-shaped plate, and the right arm is provided with an opening, wherein the arc-shaped plate moves within the opening, and the right arm is provided with a slide, which is slidably connected to a limiting mechanism, wherein the limiting mechanism is used to limit the movement of the arc-shaped plate;

[0008] Furthermore, the limiting mechanism includes a limiting box with an upper cover above it. A latch is installed inside the limiting box, wherein the bottom end of the latch extends into the opening and is inserted into the incision. A pad is provided at one end of the latch. The operator simply pulls up the latch, and when the angle between the left and right arms is at the appropriate position, lowers the latch and inserts it into any incision. This limits the displacement of the curved plate, that is, the angle between the left and right arms cannot change, thereby stabilizing the position of the clamping arms that hold the skin open. This avoids operational errors caused by device shaking during surgery or other medical procedures, providing better safety for patients and operators.

[0009] Furthermore, a spring is sleeved on the latch and acts between the backing plate and the upper cover. The compression and release strokes of the spring provide the latch with an automatic reset function.

[0010] Furthermore, sliders are provided at both ends of the bottom of the limit box, which are slidably engaged with the slideway. With the cooperation of the sliders and the slideway, the limit box can slide freely on the right arm. To slide the limit box, the latch must first be pulled up so that the lowest end of the latch enters the interior of the limit box, that is, the latch is disengaged from the opening and the cutout. Then, the limit box is pushed backward. At this time, the latch is pressed against the surface of the right arm under the thrust provided by the spring, which increases the static friction of the slider on the slideway. When the limit box is in the prohibited position, it is not easy to slide freely, and thrust must be applied to promote the displacement of the limit box, thereby improving the convenience of operation.

[0011] Furthermore, an extension arm is provided on one side of the limit box. One end of the extension arm fits against the outside of the right arm. This allows for easier operation by simply using other fingers to apply force to the limit box. The extension arm fits against the outside of the right arm, preventing conflict when the left and right arms merge.

[0012] The technical solution of this utility model has the following beneficial effects:

[0013] 1. When adjusting the angle between the left and right arms, the spring is compressed; once the latch is released, the spring immediately releases its stored energy, pushing the latch back into the incision quickly and accurately. The angle between the left and right arms cannot be changed, thereby stabilizing the position of the clamping arm to open the skin area, avoiding operational errors caused by equipment shaking during surgery or other medical procedures, and providing better safety protection for patients and operators.

[0014] 2. With the cooperation of the slider and the slide, pull up the pin so that the lowest end of the pin enters the inside of the limit box, that is, the pin is separated from the opening and the incision; then the limit box is displaced backward by the force of the extension arm; finally, use your fingers to open the angle between the left arm and the right arm to the appropriate position, and then push the limit box back to its original position by pushing the extension arm, that is, the pin is re-limited on the opening and the incision, completing the expansion of the skin area. The operation is convenient and there is no need to frequently adjust the nut. BRIEF DESCRIPTION OF THE DRAWINGS

A latch 33 is installed inside the limit box 31, wherein the bottom end of the latch 33 extends into the opening 36 and is inserted into the cutout 21. A pad 34 is provided at one end of the latch 33.

[0025] In the above solution, the operator simply pulls up the latch 33, and when the angle between the left arm 10 and the right arm 11 is at the appropriate position with their fingers, lowers the latch 33. The latch 33 is inserted into any of the incisions 21, thereby limiting the displacement of the curved plate 20. That is, the angle between the left arm 10 and the right arm 11 cannot change, thereby stabilizing the position of the clamping arm 12 in the area of ​​the skin being stretched. This avoids operational errors caused by equipment shaking during surgery or other medical procedures, providing better safety for patients and operators. Multiple incisions 21 are provided on the curved plate 20, so the latch 33 can be inserted into different incisions 21 to accommodate different angle requirements.

[0026] Further references Figure 3 , a spring 37 is sleeved on the latch 33, and the spring 37 acts between the pad 34 and the upper cover 32. The compression and release stroke of the spring 37 provide the latch 33 with an automatic reset function.

[0027] In the above solution, when the operator pulls the latch 33 to adjust the angle between the left arm 10 and the right arm 11, the spring 37 is compressed. Once the latch 33 is released, the spring 37 immediately releases its stored energy, pushing the latch 33 back into the notch 21 quickly and accurately. The elastic force of the spring 37 acts on the latch 33, making it fit more tightly within the notch 21, thereby enhancing the retaining effect of the retaining mechanism. This tight fit not only improves the stability of the device but also reduces the risk of accidents caused by the latch 33 becoming loose.

[0028] Further references Figure 3 Slide blocks 35 are provided at both ends of the bottom of the limit box 31 , and the slide blocks 35 are slidably fitted on the slideway 30 .

[0030] Further references Figure 3 An extension arm 38 is provided on one side of the limit box 31 , wherein one end of the extension arm 38 is attached to the outside of the right arm 11 .

[0031] In the above scheme, the use of the extension arm 38 allows the extension arm 38 to be directly moved or pushed by other fingers when the limit box 31 needs to be pushed, thereby improving the convenience of operation; the extension arm 38 is arranged to fit the outside of the right arm 11, which can avoid conflict between the left arm 10 and the right arm 11 when they are merged.

[0032] The specific implementation process of this embodiment is as follows:

[0033] Working method 1: Pull up the latch 33, and when the angle between the left arm 10 and the right arm 11 is at a suitable position with the fingers, lower the latch 33 and insert the latch 33 into any incision 21, thereby limiting the displacement of the arc plate 20, that is, the angle between the left arm 10 and the right arm 11 cannot be changed, thereby stabilizing the position of the clamping arm 12 to open the skin part.

[0034] Working mode 2: With the cooperation of the slider 35 and the slide 30, pull up the pin 33 so that the lowest end of the pin 33 enters the interior of the limit box 31, that is, the pin 33 is disengaged from the opening 36 and the incision 21; then the limit box 31 is displaced backward by the force of the extension arm 38; finally, the fingers open the angle between the left arm 10 and the right arm 11 to a suitable position, and then the limit box 31 is returned to its original position by pushing the extension arm 38, that is, the pin 33 is re-limited on the opening 36 and the incision 21, completing the stretching of the skin area.
