Description

Apparatus for measuring the thickness of a subject in the abdominal cavity and an apparatus for gastrectomy including the same

The present application relates to an apparatus for measuring the thickness of a subject in the abdominal cavity and a gastrectomy surgical apparatus including the same. In particular, the present application relates to an apparatus for measuring the thickness of a gastric wall incision and a gastrectomy surgical apparatus including the same for determining the size of a stapler for resection and suturing of the stomach wall in consideration of the thickness of the resection surface of the patient's stomach wall.

As the number of obese patients worldwide increases, the number of patients undergoing bariatric surgery is also increasing. Currently, the only treatment method that is evaluated to be practically effective for highly obese patients is surgery, and the demand for it is gradually increasing in Korea. In particular, the government announced the National Obesity Management Comprehensive Measures in July 2018 and promoted the reimbursement of health insurance for surgery for severe obesity, so that from January 2019, health insurance will be applied to all types of surgery for severe obesity that are performed for treatment purposes. did It is analyzed that this is to alleviate the burden of medical expenses and induce active treatment of the people due to the recent trend of increasing obesity among people in their 20s and 30s.

Bariatric surgery for highly obese patients is specifically divided into a restriction method that largely limits intake, an absorption suppression method that suppresses absorption, and a mixed method. Among them, sleeve gastrectomy (SG) is a representative dietary restriction procedure along with gastric band surgery, but it is an effective surgical method that has recently been proven effective in metabolic diseases such as diabetes by causing changes in intestinal hormones and intestinal motility. In this gastrectomy, the large curve of the stomach and the bottom of the stomach are removed and transformed into a tube with a small curve to have a volume of about 80mL to 120mL. Although the operation itself is not technically complicated and the procedure is simple, leakage When complications such as such occur, treatment is not easy and in some cases life-threatening. In order to maximize the effect of restricting food, it is necessary to leave as small a volume of the stomach as possible. However, as the diameter of the stomach after resection is smaller, the pressure in the stomach increases and thus the risk of leakage increases. Therefore, it is necessary to determine the appropriate degree of gastrectomy between the best effect of food restriction and the least complications. Although no definitive cause has been established for leakage, other than an increase in intragastric pressure, a lack of blood supply, an automatic anastomosis problem, and an unexpected stenosis problem are generally pointed out as the causes.

In particular, with respect to the automatic anastomosis machine used for sleeve gastrectomy (gastrectomy), sleeve gastrectomy uses an automatic anastomosis (suturing) machine equipped with a stapler to excise the patient's stomach in the longitudinal direction (longitudinal direction), In general, the staples (steel needles) installed in the automatic anastomosis machine are consumed, and with one use, about 6 cm of the stomach is excised and sutured. In particular, when using the automatic anastomosis machine, it is required that the operator (operator) select a stapler of an appropriate standard according to the thickness of the resection surface in consideration of the thickness of the patient's stomach wall. If an inappropriate stapler standard (length, depth, etc.) is used, as described above, there is a risk of gastric contents leaking and tissue damage. In general, the standard of the stapler was only selected depending on the experience of the surgeon. In particular, in order to prevent leakage of gastric contents, there are cases where additional suturing is performed in addition to the use of a stapler, but it was not possible to completely prevent leakage.

In other words, when performing sleeve gastrectomy, if a stapler of an appropriate size is selected according to the thickness of the gastric wall resection and suturing and resection are performed, unexpected accidents can be reduced. and the development of technology for rapid measurement is required.

In addition, according to an embodiment of the present application, the sensor unit (not shown) may be provided in an array type in which a plurality of pressure sensors are spaced apart from each other at a predetermined distance along the surface direction of the contact surface. As such, the uniformity of the subject 1 may be calculated by the sensing results of the plurality of pressure sensors respectively disposed at the plurality of positions.

In addition, according to an exemplary embodiment of the present application, the measurement unit 130 determines the uniformity of the subject 1 based on at least one of a pressure sensing result of the above-described sensor unit (not shown) and a tilting angle of the contact member 131 . can be calculated.

According to one embodiment of the present application, the uniformity of the subject 1 is the thickness in the front-rear direction or the surface direction of the base 120 of the subject 1 interposed between the base part 120 and the contact member 131 . It may mean distribution, roughness, and the like. According to an embodiment of the present application, the greater the tilt angle of the contact member 131 or the greater the deviation of the sensed pressure distribution for each measurement position, the greater the object 1 may be determined to be non-uniform, and such object ( The uniformity of 1) can be used to assist the operator in determining the appropriate resection surface or the resection direction, the staple 2 insertion direction, and the like.

The foregoing description of the present application is for illustration, and those of ordinary skill in the art to which the present application pertains will understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present application. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a dispersed form, and likewise components described as distributed may be implemented in a combined form.

The scope of the present application is indicated by the following claims rather than the above detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present application.
