Description
Technical Field
The invention belongs to the technology of medical instruments, and particularly relates to a single-suture endoscope anastomat.
Background
The general principle of the endoscope anastomat in the current market is that an I-shaped knife pulls a nail chopping board, cutting is carried out simultaneously in the closing and sewing process, and in actual use, the following problems easily occur under the design condition: (1) if the situations of poor staple forming and serious blood seepage occur after tissue suturing, an operator cannot use the product for repairing the seam, and the difficulty of using other products for repairing the seam is higher; (2) the mending of other products has limitations, such as prolonged operation time due to the large length of the wound and pain of the patient. At present, an endoscopic stapler suitable for solving the problems is not available.
Disclosure of Invention
The invention aims to provide the single-suture endoscope anastomat which breaks the structure of the I-shaped knife and is more convenient and faster in suture repairing operation based on the problems.
The technical scheme is as follows: the invention relates to a single-suture endoscope anastomat which comprises a nail anvil assembly, a nail bin assembly, a nail pushing sliding block and a pushing sheet, wherein the nail anvil assembly is arranged on the nail bin assembly; the nail anvil component is a linkage component formed by a supporting bar penetrating through the nail anvil cover, a spring plate and the nail anvil; the nail bin assembly comprises a nail bin, and the nail pushing sliding block is arranged between the nail bin and the pushing piece; the upper surface of the propelling piece is provided with a propelling piece groove, and the supporting bar is hooked and buckled in the propelling piece groove after penetrating through the nail anvil cover, the elastic sheet and the nail anvil; the free ends of the nail bin and the nail anvil are provided with plug components which are connected in a matching way.
Furthermore, the nail anvil is provided with a nail anvil chute, the elastic sheet is a V-shaped piece, the middle part of the nail anvil is provided with an elastic sheet groove, the free end of the nail anvil cover is provided with a through hole, the support bar penetrates through the nail anvil cover, the free end of the support bar is also provided with a convex block, the convex block is embedded into the through hole at the free end of the nail anvil cover, the other end of the support bar is provided with a bent part and a reset hook, and the bent part of the support bar sequentially penetrates through the elastic sheet groove and the nail; the reset hook is buckled in the groove of the propelling piece.
Furthermore, the plug component comprises a first connecting piece arranged at the free end of the nail bin and a second connecting piece matched with the free end of the nail anvil.
Furthermore, the first connecting piece is a lug, and the second connecting piece is a through hole which is matched and sleeved with the lug.
The support bars are integrally formed.
The structures or components and the connection relationship thereof which are not illustrated in the invention can be realized by the design of the endoscope anastomat in the prior art.
The working principle is as follows: when the single-suture endoscope anastomat is used, the pushing sheet is used as a power source to drive the pushing nail sliding block and the supporting strip, but the tissue cutting effect is not achieved, namely the cutting edge and the cutting knife pin of the I-shaped knife with the traditional structure are removed; because the tissue suturing in-process, the anastomotic nail shaping needs to have sufficient holding power, the support bar has replaced traditional I-shaped sword structure, at the in-process of subassembly percussion, the propulsion piece is closed, impels the support bar, impels the nail slider as the power supply with the nail anvil in proper order to pull back the support bar in proper order, the nail anvil is bounced off when reseing, realizes closed and opening, through calculating the closed stroke of nail anvil when closed, the embolism action is accomplished to the embolism subassembly, thereby accomplish the normal shaping of anastomotic nail, accomplish the mending. The closing of the nail anvil head is that the nail anvil head obliquely pushes against the tail part of the nail anvil in the triggering process of the propelling plate, the tail part of the nail anvil rises from the initial lowest point (which is pushed against the bottom surface of the opening of the propelling plate) to the highest point (which is the upper surface of the propelling plate), and the closing angle of the nail anvil rotates by 30 degrees; when the nail anvil is closed, the pushing sheet is continuously triggered, the support bar resetting hook positioned at the tail end of the nail anvil contacts the inclined plane at the rear side of the groove of the pushing sheet, so that the support bar is driven to be triggered forwards until the support bar is bolted into the nail bin sleeve, and at the moment, the assembly completes the whole closing action; in the sewing process, the propelling piece is continuously triggered, the supporting strip is bolted into the nail bin sleeve to form positioning, and the supporting strip climbs to the upper surface of the propelling piece by the elasticity of the nail bin shell, so that the phenomenon that the propelling piece is blocked cannot occur. The anvil head of the nail is opened by pulling back the pushing sheet after the sewing of the component is finished, and the support strip reset hook positioned on the upper surface of the pushing sheet is contacted with the step of the driving end of the pushing sheet so as to be separated from the nail bin sleeve and reset; in the process, the nail anvil is also contacted with the inclined plane of the pushing sheet and rotates for 30 degrees by the close angle of the nail anvil elastic sheet, and the assembly can still return to the initial firing state after the whole pulling-back action is finished.
Has the advantages that: compared with the prior art, the method has the following advantages: (1) when the tissue is repaired, the operation can be completed more conveniently, quickly and effectively; (2) the products with different types can be freely selected according to the requirements of the tissue to be sutured, for example, the length and the width of different tissues, and the products with different lengths and different staple rows can be selected, so that the healing of tissue wounds is facilitated.
