The invention relates to the technical field of pre-rehabilitation management methods, and discloses a pre-rehabilitation management method for a laparoscopic sleeve gastrectomy patient, which comprises the following steps: selecting proper subjects, the total number of the subjects is 120, and the subjects are divided into two groups according to a random number table method, namely 60 control groups and 60 observation groups; carrying out endoscopic sleeve gastrectomy on all patients in a selected period, carrying out conventional nursing on a control group, and carrying out preoperative pre-rehabilitation nursing on patients in an observation group; according to the pre-rehabilitation management method for the laparoscopic sleeve gastrectomy patient, preoperative pre-rehabilitation means that targeted and effective rehabilitation management is given to the patient from the time when a surgeon and the patient jointly decide an operation to the day before the operation according to the rehabilitation characteristics of diseases, the physiological environment and the body function reserve of the patient are improved, the patient can better tolerate the operation, and the patient can be better protected. The device is an important way for realizing rapid postoperative rehabilitation of a patient and is an extension of preoperative preparatory work.

The present application relates to the technical field of medical demonstration tools, and specifically relates to a weight loss surgery demonstration model, which comprises a display platform and a human gastrointestinal model arranged on the display platform, a cutting position is formed on the human gastrointestinal model, a clamping mechanism is arranged on the cutting position, a control panel and an internal power supply are arranged in the display platform, the clamping mechanism and the internal power supply are electrically connected with the control terminal, and the clamping mechanism is used for simulating the cutting and closing actions of the cutting position in the surgical process. The clamping mechanism can simulate the process of cutting and closing the cutting position by surgical instruments, which facilitates the observation of the main surgical steps of sleeve gastrectomy and Roux-en-Y gastric bypass surgery. The light-emitting layer can simulate the process of food passing through different parts of the human gastrointestinal model before and after surgery, so that the process of food intake and digestion before and after surgery can be observed. In addition, the light-emitting layer can also simulate the state of common postoperative complications of the cutting position, demonstrate postoperative bleeding or fistula of the cutting position, and has a better demonstration effect.

The utility model discloses a residual stomach volume self-adaptive control operation device in sleeve gastrectomy under a laparoscope, which relates to the technical field of medical instruments and comprises a main machine, a gas pipeline and a special balloon stomach tube. The main machine comprises a pressure intensity monitoring module and an inflation and deflation module, the specially-made balloon stomach tube is connected with the inflation and deflation module and the pressure intensity monitoring module in the main machine through a gas pipeline, the specially-made balloon stomach tube comprises a hose, an adjustable balloon is arranged at one end of the hose, and the other end of the hose is communicated with the gas pipeline. The adjustable balloon is used for supporting the stomach wall, laparoscopic sleeve gastrectomy is completed according to the shape and the size of the adjustable balloon, the volume of the residual stomach is planned before the operation, the operation curative effect is improved, the shape of the residual stomach is standardized, and serious complications of stomach sac stenosis and obstruction after the operation are reduced.

The invention relates to the technical field of medical instruments, in particular to an anastomotic stoma reinforcing and leakage preventing device for sleeve gastrectomy, which comprises a grab handle, a control frame is fixedly connected to the top of the grab handle, a driving block is fixedly connected to the side surface of the control frame, and an annular groove is formed in the left side of the control frame; a connecting block is rotatably connected to the side face of the inner wall of the annular groove, a supporting rod is fixedly connected to the left side of the connecting block, a jaw is fixedly connected to the left end of the supporting rod, and a driving button is fixedly connected to the left side of the grab handle. According to the anastomotic stoma reinforcing and leakage preventing device for sleeve gastrectomy, a T-shaped strip of a protection assembly is slidably connected into a moving groove of a grab handle, so that an L-shaped plate can stably cover the outer side of a driving button, a clamping block at the top of the L-shaped strip is embedded into a groove, it is guaranteed that the clamping block is always locked in the groove in cooperation with elastic reset force of a first compression spring, and dual protection is formed; accidental touch on the driving button in an operation is effectively avoided, and the risk of misoperation is reduced.

One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. Occlusion devices can be integrated with a catheter or tube to occlude one or more proximal or distal landmarks of a stomach and a stapling guide may be used to occlude a lateral boundary of the stomach to define a cavity. A volume of the potential resultant sleeve may be determined by inserting fluid or gas into the catheter or tube, measuring pressure, and calculating the volume of the cavity.

Surgical stapling instruments and control systems for these instruments are provided herein. A surgical stapling instrument includes an elongate shaft and an end effector having an anvil on a first jaw and a staple cartridge coupled to a second jaw. The instrument further includes a first coupler for adjusting a distance between the distal end of the anvil and the distal end of the staple cartridge and a second coupler for adjusting a distance between the proximal end of the anvil and the proximal end of the staple cartridge. This allows a user to independently adjust these distances or gaps to cope with tissue thickness variations across the length of the jaws. The instruments and control systems are particularly useful for dissecting and stapling relatively long lengths of tissue, such as for dissecting and stapling the stomach or lung in sleeve gastrectomy and pneumotomy procedures.

The invention discloses an adjustable sleeve stomach excision anastomat based on a laparoscope, and relates to the technical field of excision anastomats. The anastomat comprises an anastomat body, a gun barrel is connected to one side of the anastomat body, an execution head is arranged at one end of the gun barrel, a nail bin seat is connected to one side of the execution head, and the execution head is rotationally connected with a nail abutting seat corresponding to the nail bin seat; a supporting seat is arranged in the nail bin seat, a plurality of movable seats are arranged on the upper side of the supporting seat in a sliding fit mode, and a plurality of anastomosis nails are fixedly connected to one sides of the movable seats. The adjustable telescopic assembly is arranged in the supporting seat, the motor can rotate forwards and backwards, the adjustable telescopic assembly drives the multiple movable seats to horizontally stretch out and draw back on the supporting seat, the multiple anastomosis nails can be driven to be close to or far away from one another on the supporting seat, and the anastomosis lengths of the multiple anastomosis nails can be adjusted; the diversified requirements on the sleeve-shaped gastric resection anastomosis length in different operation scenes are met.

The present disclosure relates to a computer system and a method for estimating stomach volume. The computer system includes a memory and a processor that is communicatively coupled to the memory. The processor receives a video of the interior of a stomach and generates a map of the stomach based on the video. The processor also calculates the stomach volume based on the stomach map and detects a suture placed on the stomach during an endoscopic sleeve gastrectomy procedure that causes a change in the stomach's shape, based on the video and using a neural network. The processor further updates the stomach map based on the change in the stomach's shape and updates the calculated stomach volume based on the updated stomach map.
