Description
Technical Field
The present invention relates to, but is not limited to, the field of surgical stapling machines, and more particularly, to a tissue identification module and endoscopic stapler.
Background
Staplers are devices used in surgery to replace manual suturing, working on the principle of severing or stapling tissue with titanium staples, similar to staplers. Compared with the traditional manual suture, the instrument suture has the following advantages: the suture is quick, the operation is simple and convenient, and the operation time is saved; the disposable is used for one time, so that cross infection is avoided; titanium nails or stainless steel nails are used, and the sewing is tight and the tightness is proper; has the advantages of less side effect, less operation complication and the like, also ensures that the tumor operation which cannot be resected in the past can be resected with premonitory symptoms, and is very popular with surgeons. The application range of the instrument relates to various fields of gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology surgery, obstetrics and gynecology, and becomes one of the indispensable tools of doctors. The device has the advantages of less bleeding during operation, less operation time, reduced error caused by manual operation by replacing manual operation with instruments, infection avoidance, quick functional recovery after operation and the like.
When the nail bin of the anastomat is closed, organ tissues can be clamped, the thicknesses of tissues corresponding to different organs of a human body are different, the thicknesses of the clamped tissues are different, and even if the same organ is used, the phenomena of different thicknesses exist due to the individual difference of each person, the different positions of selected anastomosis and the like. When a doctor clinically uses the endoscope anastomat, different nail bin assemblies (different nail height suturing nails are arranged in the different nail bin assemblies) are selected to cut and suture after different organ tissue thicknesses are often required to be judged in advance. This requires the surgeon to rely on his or her own surgical experience to determine which cartridge assembly is more suitable for the operation, i.e., which staple height is selected for performing the anastomosis of the organ tissue, which presents difficulties and operational risks to the surgeon. If the tissue is too thick and the suturing nail is selected to be improperly high, the serious consequences of loose sutured tissue after the operation, bleeding and the like can be caused, and further medical accidents can occur.

Thus, when the motor 27 is activated, the output gear 28 is driven to rotate, which drives the rack 29 to move along its length, thereby moving the transmission shaft 13 along its axial direction. If the manual driving type is provided, as shown in fig. 9, in another exemplary embodiment, the connecting assembly includes a swing link 31 and a connecting rod 32, the manual control element 30, the swing link 31 and the connecting rod 32 are sequentially hinged, and one end of the connecting rod 32 is hinged to the transmission shaft 13, so that the swing of the manual control element 30 can sequentially drive the swing link 31 and the connecting rod 32 to move so as to drive the transmission shaft 13 to move along the axial direction thereof, but the invention is not limited thereto, for example, the connecting assembly can also be a multi-link assembly, etc., as long as the manual control element 30 can drive the transmission shaft 13 to move. Therefore, the transmission mechanism is driven by electricity or hand, the connecting component can drive the transmission shaft 13 to slide, and the identification process of the tissue identification module is not influenced by the structure of the connecting component.
As shown in fig. 1 to 8, a mounting groove 18 matching with the outer contour of the transmission shaft 13 is disposed at a position of the connection block 10 corresponding to the transmission shaft 13, the thin film pressure sensor 11 and the protective cover 12 are disposed at the bottom of the mounting groove 18, one end of the transmission shaft 13 is inserted into the mounting groove 18 and can be pressed against the thin film pressure sensor 11 when the connection block 10 is pushed to slide towards the front end of the rotary head assembly 3, so that the pushing force is completely pressed against the thin film pressure sensor 11, and the driving force value is accurately obtained.

In order not to affect the pressure test, when the transmission shaft 13 is pressed against the film pressure sensor 11, i.e. the connection block 10 is pushed to slide towards the front end of the rotating head assembly 3, as shown in fig. 6 and 7, a first gap 19 is provided between the connection pin 14 and the groove wall of the sliding groove 16 at the front end, i.e. the connection pin 14 and the sliding groove 16 are always in clearance fit until the cartridge is closed in place. When the connecting pin 14 pulls the connecting block 10 to slide towards the rear end of the rotating head assembly 3, as shown in fig. 4 and 5, the connecting pin 14 abuts against the wall of the chute 16 at the rear end until the nail bin is completely opened, and at this time, the end surface of the transmission shaft 13 is not in contact with the film pressure sensor 11, so that the film pressure sensor 11 is ensured not to be stressed at this time. From the above, it can be seen that the film pressure sensor 11 is disposed on the connecting block, but not limited thereto, the film pressure sensor 11 may also be mounted at other positions of the transmission mechanism, and the driving force on the transmission mechanism can be measured.
When the nail bin is closed in place, the transmission shaft 13 stops moving, the transmission mechanism is in a stress balance state, and through the principle of acting force and reaction force, the driving force of the transmission shaft 13 is equal to the reaction force on the film pressure sensor 11, and the driving force is also equal to the pressure on the tissues 25 at the anastomosis part, so that the pressure detection module indirectly detects the pressure value. In addition, the controller 8 is internally provided with a database of the corresponding relation between the pressure applied to the tissue 25 at the anastomosis site and the thickness and the suggested nail height of the tissue, the database is formed by arranging test data, and the database can be a corresponding relation table shown in fig. 11, for example, so that the controller 8 can judge the required nail height after the pressure applied to the tissue 25 at the anastomosis site is obtained, and a doctor can be reminded through a display screen. For example, when the measured pressure value Fx is 150N, the controller 8 judges that it is within the range of 100-.

In addition, the film pressure sensor 11 can be connected to the controller 8 through bluetooth or other short-range wireless communication technology to transmit pressure data. Thus, the pressure sensing module 23 is modular, similar in overall appearance to the cartridge assembly 2, and all may be removed from the same cartridge mounting location 6. When the pressure detection module 23 is installed at the cartridge installation position 6, the pressure detection module replaces the position of the cartridge assembly 2, at the moment, the cartridge is closed in place, only the pressure value can be measured, and the pressure detection module 23 does not have anastomosis nails and cannot be used for suturing and cutting. After the thickness of the anastomosed tissue is measured, a doctor can select a proper nail bin assembly 2 according to the nail height prompted by the display screen, then the pressure detection module 23 is detached from the rotating head assembly 3, the corresponding nail bin assembly 2 is replaced for installation, and then cutting and suturing are carried out.
