[0033] Compared with the prior art, the scalpel structure capable of marking positions and its forming method of the present invention have the following advantages:

[0034] 1. For the scalpel structure capable of marking positions formed by the method of the present invention, marking and measuring the edge position of the tumor, determining the scope of extended resection, and excising the tumor and its surrounding tissues can be carried out simultaneously, which not only liberates the doctor's hands but also greatly reduces the doctor's workload, making the doctor time-saving and labor-saving during the operation and improving the operation efficiency.

Thus, after confirming the edge of the tumor by using the laser pen, the scope of extended resection of the tumor edge is measured by the measuring ruler, and the tumor and the tumor surrounding tissues within the scope of extended resection are excised while measuring the scope of extended resection of the tumor edge. One set of structure realizes multiple functions, neither blocking the operation visual field range nor greatly facilitating the doctor's operation.

[0036] 3.

[0037] The present invention will be described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 is the first structural schematic diagram of the scalpel structure capable of marking positions of the present invention;

[0039] Figure 2 is the second structural schematic diagram of the scalpel structure capable of marking positions of the present invention;

[0040] Figure 3 This is the third schematic diagram of the scalpel structure at the markable position of the present invention. Detailed implementation manners

[0041] The present invention provides a method for forming a scalpel structure with a markable position, which includes:

[0042] Forming a stent that can be expanded or closed;

[0043] Detachably installing a column that can rotate relative to the stent on the stent;

[0044] Installing a laser pen for confirming the tumor margin at the lower end of the column;

[0045] Installing a measuring scale for measuring the expanded resection range of the tumor margin when confirming the tumor margin at a position near the lower end of the column;

[0046] Installing a scalpel at one end of the measuring scale for excising the tumor and the tumor peripheral tissue within the expanded resection range while the measuring scale measures the expanded resection range of the tumor margin.

[0047] Next, the method for forming the scalpel structure with a markable position of the present invention will be specifically described.

[0048] S01. Forming a stent that can be expanded or closed

[0049] Forming a stent that can be expanded or closed includes:

[0050] Forming a hollow sleeve;

[0051] At least three legs hinged to the outer periphery of the sleeve are arranged at equal angles. During application, the number of legs can be determined according to actual needs, such as using three, four or more than four legs. The structure at the hinged part of the leg and the sleeve should not only ensure the expansion and retraction of the leg relative to the sleeve, but also ensure that it can remain at the required angle after being expanded. The structure at the hinged part can adopt a similar structure in the prior art and will not be elaborated here.

[0052] In addition, forming a stent that can be expanded or closed further includes: arranging a support (such as shown in Figure 3 ) hinged to the lower end of each leg for facilitating the fitting with the support surface, so as to make the whole scalpel structure fit well with the patient's skin surface and facilitate the operation in a relatively stable environment.

[0053] During manufacturing, the legs can adopt legs with a constant length (such as shown in Figure 1 ), and can also adopt telescopic legs with adjustable length (such as shown in Figure 2 、 Figure 3As shown in FIG, the leg length can be selected according to actual needs to ensure that the support height meets the requirements, such as the requirement of not obstructing the surgical field of view. The structure of the retractable leg can refer to the structure of the retractable structural member in the prior art and will not be described in detail here.

[0054] It should be noted that, when in use, the support heights and angles of each leg relative to the sleeve can be equal, or they can be adjusted to different heights and angles according to the location of the tumor, ultimately for the purpose of facilitating surgical operations.

[0055] S02. Removably install the column that can rotate relative to the bracket on the bracket

[0056] When the column rotatable relative to the bracket is detachably mounted on the bracket, the upper end of the column can pass through the center of the sleeve and be rotatably connected to the sleeve, for example, the column and the sleeve are rotatably connected through a bearing.

[0057] Alternatively, when the column that can rotate relative to the bracket is detachably installed on the bracket, the upper end of the column can be passed through the center of the sleeve and threadedly connected to the inner wall of the sleeve, that is, an external thread is set on the outer wall of the upper part of the column, and an internal thread matching it is set at the center hole of the sleeve.

[0058] By using the above method, the column can be extended vertically downward relative to the sleeve and can rotate relative to the bracket, so that the angles of the laser pen, measuring ruler and scalpel installed on the column can be adjusted as needed during surgery, which is conducive to smooth surgery.

[0059] Furthermore, the column can also be a telescopic column with adjustable height, for example, comprising an upper column and a lower column that is sleeved with the upper column, so that the height of the upper column extending from the lower column can be adjusted accordingly according to the needs of the operation and locked at the desired height to meet the required operating height of the scalpel. Alternatively, the telescopic column can also adopt a similar structure in the prior art, which will not be described in detail here.

[0060] S03. Install a laser pen at the bottom of the column to confirm the tumor edge.

[0061] A laser pointer for determining tumor margins is mounted at the lower end of the column. The pointer can emit a laser beam downward along or parallel to the axis of the column. This laser pointer can be a cross-shaped laser pointer, accurately determining the tumor margin position through the emitted cross-shaped laser beam. During assembly, the laser pointer can be detachably mounted or fixed to the lower end of the column, and auxiliary components can be appropriately used based on actual conditions.

[0062] S04. Install a measuring ruler near the lower end of the column to measure the tumor edge and expand the resection range when confirming the tumor edge.

[0063] Installing a measuring ruler for measuring the scope of extended resection of the tumor margin when confirming the tumor margin near the lower end of the column includes:

[0064] Install a clamping seat rotatably connected to the lower end of the column. The structure of the clamping seat rotatably connected to the column can adopt existing technologies and will not be elaborated here. The clamping seat rotates relative to the column, and during the operation, the scalpel on it can be rotated by rotating the clamping seat as needed.

[0065] Install the measuring ruler on the clamping seat. When installing, in order to facilitate determining the measuring range of the distal end of the measuring ruler from the tumor margin according to requirements, the measuring ruler and the clamping seat adopt a sliding connection structure. For example, a chute perpendicular to the extending direction of the column is provided on the clamping seat, and the measuring ruler with an extending direction perpendicular to the column is placed in the chute.

[0066] S05. Install a scalpel at one end of the measuring ruler for excising the tumor and the tumor peripheral tissue within the scope of extended resection while the measuring ruler measures the scope of extended resection of the tumor margin

[0067] Install a scalpel at one end of the measuring ruler. When installing, the scalpel can be installed at the end of the measuring ruler in a detachable manner. The scalpel can adopt an existing technology with a detachable blade scalpel so that a new blade can be replaced during each operation. In addition, the scalpel can be set in different models, but different models have the same handle that can be connected to the measuring ruler.

[0068] Furthermore, when installing the scalpel at one end of the measuring ruler, the scalpel and the measuring ruler can also be connected together in a way that the scalpel can rotate relative to the measuring ruler. In this way, the angle of the scalpel relative to the measuring ruler can be rotated according to the surgical needs.

[0069] While the measuring ruler measures the scope of extended resection of the tumor margin, the tumor and the tumor peripheral tissue within the scope of extended resection can be excised through the scalpel.

[0070] In addition to providing the above method, the present invention also provides a scalpel structure with a markable position formed by the above method, such as Figures 1 - 3 As shown, they are respectively schematic diagrams of the scalpel structure with a markable position of the present invention when adopting different structures. It can be seen from the figure that the scalpel structure with a markable position of the present invention includes: a stent that can be expanded or closed; a column 4 rotatably installed on the stent; a laser pen 6 installed at the lower end of the column for confirming the tumor margin; a measuring ruler 8 installed at the lower end of the column for measuring the scope of extended resection of the tumor margin when confirming the tumor margin; a scalpel 9 installed at one end of the measuring ruler for excising the tumor and the tumor peripheral tissue within the scope of extended resection while the measuring ruler measures the scope of extended resection of the tumor margin.

[0071] Specifically, the stent of the present invention comprises: a hollow sleeve 2; and at least three legs 3, arranged at equal angles around the sleeve and hingedly connected thereto. Furthermore, to enhance the stability of the stent during surgery, the stent of the present invention may also include a hinged support 10 at the lower end of each leg, allowing it to conform to the support surface. To adjust the support height as needed, the legs of the present invention may be retractable, although non-retractable legs are also acceptable.

[0072] The upper end of the column can pass through the center of the sleeve and be rotatably connected to the sleeve, or the upper end of the column can pass through the center of the sleeve and be threadedly connected to the inner wall of the sleeve. The upper end of the column extends from the sleeve to form a handle 1 for easy gripping. During surgery, the handle can be turned to rotate the column relative to the sleeve, thereby driving the laser pointer 6, measuring ruler 8, and scalpel 9 mounted at the lower end of the column to rotate with the column, for example, 360 degrees, to facilitate the scalpel cutting the tumor and surrounding tissue.

[0073] Furthermore, the column can also be a telescopic column with adjustable height, for example, comprising an upper column and a lower column that is sleeved with the upper column, so that the height of the upper column extending from the lower column can be adjusted accordingly according to the needs of the operation and locked at the desired height to meet the required operating height of the scalpel. Alternatively, the telescopic column can also adopt a similar structure in the prior art, which will not be described in detail here.

[0074] A clamping base 5, pivotally connected to the lower end of the column, is mounted on the clamping base. The measuring ruler is designed to slide between the two. When the ruler is moved to the desired position relative to the clamping base, a locking member 7 locks the ruler to the clamping base, securing the distal end of the ruler in the correct position for a scalpel cut. The locking member features a locking screw, perpendicular to the length of the ruler. A corresponding through-hole for the locking screw is provided in the clamping base. The locking screw passes through the through-hole and presses against the ruler held by the clamping base, preventing the ruler from moving relative to the clamping base.

[0075] During assembly, the laser pen can be installed at the bottom of the clamping base or on the column. The laser pen can be coaxial with the column. When in use, a cross laser pen can be used to emit a cross-shaped light that does not hurt the skin. The use of cross positioning can ensure that the tumor edge measured by the measuring ruler and the expanded resection range are reasonable, and ensure that the cutting position of the scalpel meets the Mohs surgical cutting requirements.

[0076] One end of the measuring ruler is equipped with a scalpel, which is installed at the end of the measuring ruler in a detachable manner. For example, a clamping seat is provided at the end of the measuring ruler, and the handle of the scalpel is clamped with the clamping seat. Further, the clamping seat can also be rotatably connected to the end of the measuring ruler. In this way, the angle of the clamping seat and the clamped scalpel relative to the measuring ruler can be rotated according to the surgical needs. The scalpel can adopt a scalpel with a detachable blade in the prior art so that a new blade can be replaced during each operation. In addition, the scalpel can be set in different models, but different models have the same handle that can be connected to the measuring ruler.

[0077] Next, the usage process of the scalpel structure capable of marking positions according to the present invention will be described.

[0078] 1. According to the location of the tumor and the surgical needs, fix the bracket on the patient's skin so that the intersection point of the cross laser beam emitted by the positioned laser pen can be aligned with the proximal end of the measuring ruler located at the edge of the tumor or a preset distance from the proximal end of the measuring ruler, such as 0.3 cm, or adjust the corresponding distance according to the scope of the disease. Here, the proximal end of the measuring ruler refers to the end close to the tumor.

[0079] 2. According to the predetermined extended resection range of the tumor edge, move the measuring ruler and use its distal end to determine the fixed position of the peripheral range of the tumor to be cut.

[0080] 3. After determining the fixed position of the peripheral range of the tumor to be cut through the measuring ruler, rotate the scalpel one week to cut the tumor and the surrounding tissues through the scalpel.

[0081] In summary, the scalpel structure capable of marking positions formed by the method of the present invention has a simple structure and is convenient to use. The entire scalpel structure can be stably supported outside the tumor tissue by using the bracket, enabling the operation to be carried out in a relatively stable environment; after confirming the tumor edge by using the laser pen, the extended resection range of the tumor edge is measured through the measuring ruler, and at the same time when the extended resection range of the tumor edge is measured, the tumor and the tumor peripheral tissues within the extended resection range can be resected. One set of structure realizes multiple functions, greatly facilitating the surgical operation of doctors.

[0082] Although the present invention has been described in detail above, the present invention is not limited thereto. Those skilled in the art of this technology can make modifications according to the principle of the present invention. Therefore, all modifications made according to the principle of the present invention should be understood to fall within the protection scope of the present invention.
