Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a skin tissue biopsy shovel. Background Technology

[0002] For skin tissue biopsies of some superficial skin masses, only a portion of the superficial tissue needs to be removed. In such cases, using existing scalpels and trephines for tissue sampling is quite limited, failing to meet the need for convenient longitudinal and transverse incisions. Furthermore, it is difficult to effectively determine the depth of tissue removal and obtain an incision (approximately 30-degree incision angle) conducive to suturing, resulting in overall operational limitations and low efficiency. Therefore, we propose a skin tissue biopsy shovel to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a skin tissue biopsy shovel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A skin tissue biopsy shovel includes a blade and a rod. One end of the blade is detachably and fixedly connected to one end of the rod. The other end of the blade is provided with a slicing blade with an arc-shaped curved edge. Both sides of the blade are provided with length markings. The rod is provided with an auxiliary positioning mechanism.

[0006] Preferably, a handle is fixed to the end of the rod away from the cutter head.

[0007] Preferably, the rod body is further provided with an auxiliary positioning mechanism, which includes a first limiting member and a connecting frame. The first limiting member includes a first limiting block and a second limiting block. The first limiting block and the second limiting block can be joined together and snapped together. The rod body can be positioned between the first limiting block and the second limiting block, and the first limiting block and the second limiting block can slide vertically to limit the rod body. The connecting frame is inverted L-shaped, with one end of the connecting frame fixedly connected to the first limiting block and the other end of the connecting frame fixedly connected to a base plate.

[0008] Preferably, one end of the base plate is provided with a first arc-shaped surface, and a U-shaped block is detachably connected to one end of the base plate corresponding to the first arc-shaped surface. The inner side of the opening of the U-shaped block is provided with a second arc-shaped surface corresponding to the arc-shaped surface. After the U-shaped block is connected to the base plate, a slot is formed, and the cutting head can be perpendicular to the middle position of the slot.

[0009] Preferably, the length of the rod is longer than the height of the connecting frame, and the thickness of the U-shaped block is the same as the thickness of the base plate.

[0010] Preferably, a handle is fixed on the base plate.

[0025] Example 1

[0026] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 4 A skin tissue biopsy shovel includes a blade head 1 and a rod body 2. One end of the blade head 1 is detachably and fixedly connected to one end of the rod body 2, allowing the blade head 1 to be disassembled and removed. The other end of the blade head 1 is equipped with a slicing blade 3, the edge of which is curved. Both sides of the blade head 1 are provided with length markings 4. The slicing blade 3 is used to cut skin tissue from the patient, and the length markings 4 help medical personnel to determine the depth of tissue cutting.

[0027] For the above example, those skilled in the art should know that when implementing the above technical solution, a screw can be provided at one end of the rod body 2, and the cutter head 1 is provided with a screw hole that matches the screw thread. The rod body 2 is threadedly fixedly connected to the cutter head 1 through the screw and the screw hole, that is, the effect of detachable fixed connection is achieved.

[0028] For the above example, those skilled in the art should know that when implementing the above technical solution, the cutter head 1 can be set with a variety of specifications and sizes, which can be selected according to the needs, and installed with the rod body 2.

[0029] As a technical optimization of this utility model, a handle 5 is fixed to the end of the rod 2 away from the blade head 1. The handle 5 is easy for medical personnel to hold, thereby facilitating the operation of the rod 2 and the corresponding blade head 1 for skin tissue removal. The rod 2, together with the blade head 1, can meet the requirements of longitudinal or transverse tissue cutting operations. Longitudinal cutting is a vertical downward cutting operation.

[0030] The slicing blade 3 of the blade head 1 of this device has an arc-shaped curved edge with an angle of approximately 15 degrees, as shown in the figure below. Figure 3As shown, during a vertical downward cut, two longitudinal cuts made face-to-face can create an incision with an angle of approximately 30 degrees, facilitating subsequent suturing. Specifically, as shown... Figure 4 As shown.

[0031] The working principle is as follows:

[0032] Medical staff can easily operate the handle 5 to perform skin tissue removal by manipulating the rod 2 and the corresponding blade 1. The rod 2, in conjunction with the blade 1, can perform longitudinal or transverse tissue removal. It allows for two-stage, face-to-face removal, meaning the tissue to be removed is cut vertically from both sides once. After these two longitudinal cuts, an incision with an angle of approximately 30 degrees is obtained, facilitating subsequent suturing and repair. Furthermore, the length markings 4 help medical staff clearly determine the depth of tissue removal when harvesting the patient's skin tissue.

[0033] Example 2

[0034] Reference Figure 5 The difference between this embodiment and Embodiment 1 is that:

[0035] The rod 2 is also equipped with an auxiliary positioning mechanism, which includes a first limiting member and a connecting frame 6. The first limiting member includes a first limiting block 7 and a second limiting block 8, which can be locked together. The rod 2 can be positioned between the first limiting block 7 and the second limiting block 8, and the rod 2 can slide vertically between the first limiting block 7 and the second limiting block 8. The connecting frame 6 is inverted L-shaped, with one end fixedly connected to the first limiting block 7 and the other end fixedly connected to a base plate 9. During the incision, the base plate 9 is used to abut against the patient's skin, and the first limiting block 7 and the second limiting block 8 can restrict the rod 2, keeping it perpendicular to the patient's skin surface. At this time, pressing down on the rod 2 can effectively ensure the stability of the rod 2.

[0036] One end of the base plate 9 is provided with a first arc-shaped surface. A U-shaped block 10 is detachably connected to one end of the base plate 9 corresponding to the first arc-shaped surface. The inner side of the opening of the U-shaped block 10 is provided with a second arc-shaped surface corresponding to the arc-shaped surface. After the U-shaped block 10 is connected to the base plate 9, a slot is formed. The cutter head 1 can be perpendicular to the middle position of the slot. The slot facilitates positioning.

[0037] The length of the rod 2 is longer than the height of the connecting frame 6, and the thickness of the U-shaped block 10 is the same as the thickness of the base plate 9. A handle 11 is fixed on the base plate 9. The handle 11 facilitates pressing down on the base plate 9 to ensure its stability. A rubber layer 12 is provided at the bottom of the base plate 9, which provides both flexible contact and anti-slip properties.

[0038] The second arc-shaped surface of the U-shaped block 10 is fitted with a side plate 13, which slides vertically with the U-shaped block 10. The length of the side plate 13 is longer than the thickness of the U-shaped block 10. The U-shaped block 10 can serve as a positioning tool. When it is necessary to perform a vertical downward cutting operation on both sides of the tissue to be removed, the side plate 13 can be pressed down after positioning, leaving a pressure mark on the patient's skin. This mark corresponds to the second arc-shaped surface. After cutting on one side, the base plate 9 and the U-shaped block 10 are rotated, so that the corresponding blade 1 also rotates its position, and the corresponding slot also rotates its position. At this time, it is necessary to ensure that the first arc-shaped surface is aligned with the mark, thereby achieving an auxiliary alignment effect, which facilitates the cutting operation on the other side.

[0039] The working principle is as follows:

[0040] During the downward cut, the handle 11 controls the base plate 9 to press against the patient's skin. The first limiting block 7 and the second limiting block 8 are used to limit the rod 2, keeping the rod 2 perpendicular to the patient's skin surface. Pressing down on the rod 2 at this time effectively ensures its stability. When it is necessary to perform a vertical downward cut on each side of the tissue to be removed, after positioning the base plate 9, the side plate 13 is pressed down, leaving a pressure mark on the patient's skin. This mark corresponds to the second arc-shaped surface. After cutting on one side, the base plate 9 and the U-shaped block 10 are rotated, so that the corresponding blade 1 also rotates its position, and the corresponding slot also rotates its position. At this time, the first arc-shaped surface is aligned with the mark, and the downward cut is performed on the other side. This achieves an auxiliary alignment effect and effectively improves work efficiency.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
