Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anastomat, in particular to an anastomat with pre-closing function. BACKGROUND

[0002] Anastomat is also called suturing device in medicine, which is mainly used for gastrointestinal anastomosis. Its function is similar to that of a stapler, and its effect is very significant in clinical use. The principle is to retain good physiological tissue, cut and remove the pathological tissue, and then instantly anastomose the cut part. This method can not only block the blood supply of the operation site, but also quickly suture the incision and shorten the operation time. It can restore the physiological tissue to the normal anatomical state, and is favored and respected by clinical surgeons at home and abroad.

[0003] Because the anastomat cuts the tissue by using a knife to cut and separate the tissue, there is always bleeding at the anastomotic site during clinical use. Generally, the bleeding is small, but sometimes there is a lot of bleeding, which causes some patients to need a second emergency operation. Therefore, an anastomat that can ensure hemostasis of the wound is needed. SUMMARY

[0004] The present application aims at the shortcomings of the above-mentioned existing production technology, and provides an anastomat with pre-closing function, which combines electrocoagulation, hemostasis, suturing and cutting to maximize the reduction of postoperative wound bleeding and avoid the situation of excessive bleeding requiring a second emergency operation.

[0005] The technical scheme adopted by the present application is as follows: An anastomat with pre-closing function is composed of a clamp head, a sleeve and a handle connected in sequence. The clamp head includes a nail cartridge seat and a nail abutting seat arranged in upper and lower correspondence. One end of the nail cartridge seat and one end of the nail abutting seat are connected to a clamp head mounting seat, and the clamp head mounting seat is connected to one end of the sleeve. A titanium nail cartridge is arranged at the bottom of the nail cartridge seat. An upper insulating seat is arranged above the titanium nail cartridge. An upper electrode piece is arranged on the upper insulating seat. The upper electrode piece is composed of a plurality of upper electrode segments. A lower insulating seat is arranged in the nail abutting seat. A lower electrode piece is arranged on the lower insulating seat. The lower electrode piece is composed of a plurality of lower electrode segments. The plurality of upper electrode segments and the plurality of lower electrode segments are arranged in one-to-one upper and lower correspondence. Each upper and lower corresponding upper electrode segment and lower electrode segment corresponds to a measurement position. A control panel is arranged in the handle. Each upper electrode segment is connected to the control panel through an upper lead wire. Each lower electrode segment is connected to the control panel through a lower lead wire. An upper electrode segment and a lower electrode piece arranged in upper and lower correspondence can form a measurement resistance loop between them, so that a plurality of measurement resistance loops are formed between the upper electrode piece and the lower electrode piece.

[0006] Furthermore, a recessed upper positioning groove is provided inside the upper insulating seat, and an upper electrode plate is provided in the upper positioning groove. An upper cutting groove is provided in the middle of the upper insulating seat along the length direction, and the upper cutting groove divides the upper insulating seat and the upper electrode plate into two parts.

[0007] Furthermore, an upper insulating spacer is provided at the contact portion of two adjacent upper electrode segments for insulation isolation. The upper insulating spacer is glued to the upper electrode segment, and multiple upper electrode segments are connected to form a whole.

[0008] Furthermore, multiple upper insulating partitions are arranged along the length of the upper positioning groove, and the multiple upper insulating partitions divide the upper positioning groove into multiple upper positioning chambers, with a corresponding upper electrode segment arranged in each upper positioning chamber.

[0009] Furthermore, a recessed lower positioning groove is provided inside the lower insulating seat, and a lower electrode plate is placed in the lower positioning groove. A lower cutting groove is provided in the middle of the lower insulating seat along the length direction, and the lower cutting groove divides the lower insulating seat and the lower electrode plate into two parts.

[0010] Furthermore, a lower insulating spacer is provided at the contact portion of two adjacent lower electrode segments for insulation isolation. The lower insulating spacer is glued to the lower electrode segment, and multiple lower electrode segments are connected into a whole.

[0011] Furthermore, multiple lower insulating partitions are arranged along the length of the lower positioning groove, which divide the lower positioning groove into multiple lower positioning chambers, and a lower electrode segment is arranged in each lower positioning chamber.

[0012] Furthermore, through holes are provided on the upper electrode segment, which are used for titanium nails to pass through.

[0013] Furthermore, multiple upper electrode segments are arranged sequentially along the length direction of the upper insulating base, and multiple lower electrode segments are arranged sequentially along the length direction of the lower insulating base.

[0014] Furthermore, the upper and lower conductors are installed inside the sleeve.

[0015] The beneficial effects of this invention are as follows: This invention features electrode pads on the upper and lower end faces of the stapler's clamp head, combining electrocoagulation, hemostasis, suturing, and cutting to minimize postoperative bleeding and prevent secondary emergencies due to excessive bleeding. The electrode pads are segmented, with a pair of corresponding segments forming a resistance measurement circuit. Different currents are output for different tissue thicknesses at each measurement location, ensuring good pre-closure even for tissues of varying thicknesses and preventing suturing failure due to excessive tissue thickness. Furthermore, the segmented electrode pads are insulated and positioned using an insulating structure, guaranteeing proper electrode operation. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of the present invention will now be described with reference to the accompanying drawings. Example 1:

[0028] like Figure 1 As shown, a stapler with a pre-closing function is composed of a clamp head 100, a sleeve 200 and a handle 300 connected in sequence.

[0029] like Figure 2As shown, the pliers head 100 includes a staple cartridge seat 101 and a staple abutment seat 102 arranged correspondingly on the upper and lower sides. One end of the staple cartridge seat 101 and one end of the staple abutment seat 102 are connected to the pliers head mounting seat 103, which is connected to one end of the sleeve 200.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, a titanium nail cartridge 112 is disposed at the bottom of the nail cartridge holder 101, and an upper insulating seat 104 is disposed above the titanium nail cartridge 112. An upper electrode plate is disposed on the upper insulating seat 104. The upper electrode plate is composed of multiple upper electrode segments 106, which are arranged sequentially along the length direction of the upper insulating seat 104.

[0031] like Figure 5 As shown, an upper insulating spacer 108 is provided at the contact portion of two adjacent upper electrode segments 106 for insulation isolation. The upper insulating spacer 108 is glued to the upper electrode segment 106, so that multiple upper electrode segments 106 are connected to form a whole, which facilitates the installation of the upper electrode sheet.

[0032] like Figure 5 As shown, the upper electrode segment 106 is provided with a through hole 115 that runs vertically through it, and the through hole 115 is used for titanium nails to pass through.

[0033] like Figure 3 and Figure 4 As shown, a recessed upper positioning groove 110 is provided inside the upper insulating seat 104, and an upper electrode plate is disposed in the upper positioning groove 110. An upper cutting groove 113 is provided in the middle of the upper insulating seat 104 along the length direction, and the upper cutting groove 113 divides the upper insulating seat 104 and the upper electrode plate into two parts.

[0034] like Figure 6 , Figure 7 and Figure 8 As shown, a lower insulating seat 105 is provided inside the anvil seat 102, and a lower electrode plate is provided on the lower insulating seat 105. The lower electrode plate is composed of multiple lower electrode segments 107, which are arranged sequentially along the length of the lower insulating seat 105. Multiple upper electrode segments 106 and multiple lower electrode segments 107 are arranged in a one-to-one correspondence, and each corresponding upper electrode segment 106 and lower electrode segment 107 corresponds to a measurement position.

[0035] like Figure 8 As shown, the contact portion of two adjacent lower electrode segments 107 is provided with a lower insulating spacer 109 for insulation isolation. The lower insulating spacer 109 is glued to the lower electrode segment 107, so that multiple lower electrode segments 107 are connected into a whole, which facilitates the installation of the lower electrode sheet.

[0036] like Figure 6 and Figure 7As shown, a recessed lower positioning groove 111 is provided inside the lower insulating base 105, and a lower electrode plate is disposed in the lower positioning groove 111. A lower cutting groove 114 is provided in the middle of the lower insulating base 105 along the length direction, and the lower cutting groove 114 divides the lower insulating base 105 and the lower electrode plate into two parts.

[0037] like Figure 1 As shown, a control board 118 is installed inside the handle 300. Each upper electrode segment 106 is connected to the control board 118 via an upper wire, and each lower electrode segment 107 is connected to the control board 118 via a lower wire. A resistance measurement loop can be formed between a corresponding upper electrode segment 106 and a corresponding lower electrode segment 107, thus creating multiple resistance measurement loops between the upper and lower electrode plates. The upper and lower wires are installed inside the sleeve 200.

[0038] The handle 300 also contains a power supply for the anastomosis device. The power supply is electrically connected to the control board 118. During anastomosis, the power supply provides power to the circuit of each measuring resistor. Then, based on the different tissue thicknesses at each measuring position, it feeds back different current signals to the control board 118. The control board 118 calculates the resistance value at each measuring position based on the different current signals, and then adjusts the output current at that position based on the resistance value. This allows for different current outputs at each measuring position based on the different tissue thicknesses, ensuring that tissues of different thicknesses can achieve a good pre-closure effect and avoiding suturing failure due to excessive tissue thickness. Example 2:

[0039] like Figure 9 and Figure 10 As shown, the difference from Embodiment 1 is that multiple upper insulating partitions 116 are arranged along the length direction within the upper positioning groove 110, dividing the upper positioning groove 110 into multiple upper positioning compartments, each of which contains a corresponding upper electrode segment 106. Similarly, multiple lower insulating partitions 117 are arranged along the length direction within the lower positioning groove 111, dividing the lower positioning groove 111 into multiple lower positioning compartments, each of which contains a corresponding lower electrode segment 107.

[0040] During installation, the upper insulating partition 116 and the lower insulating partition 117 can facilitate the positioning and installation of the upper and lower electrode segments 106 and 107, and at the same time, can achieve insulation isolation between two adjacent electrode segments.
