Medical anastomat detection device

Abstract

The invention discloses a medical anastomat detection device. The medical anastomat detection device comprises a conveying guide rail, an electric measuring contact, an electric measuring contact moving mechanism, a shooting device, a third die holder blocking mechanism and a turnover plate mechanism, wherein the electric measuring contact comprises a contact pedestal, a plurality of pairs of electrodes corresponding to nail grooves in an anastomat die holder are fixedly arranged at the top of the contact pedestal, the bottoms of the electrodes are all fixed in the contact pedestal, and the tops of the electrodes extend out of the contact pedestal. According to the medical anastomat detection device, by arranging the electric measuring contact, the electric measuring contact is matched with anastomosis nails in an anastomat to form an equivalent capacitance circuit or a switch circuit, the embedding integrity of the anastomosis nails in the anastomat can be detected by measuring the equivalent capacitance value or the state of the switch circuit, the detection is reliable, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of medical equipment production, in particular to a detection device for a medical stapler. Background technique [0002] In the medical and clinical field, a stapler is a device used for suturing wound epidermis and coelenteric incision. The device is mainly composed of a mold base and staples. In the application of clinical operations, the staples are pushed out from the mold base by special tools and nailed through the skin of the wound and the tissues on both sides of the coelenteric incision, so as to rivet the skin and deep tissues on both sides of the wound together, so as to facilitate the healing of human tissues recover. If there is a lack of staples in the finished stapler, it will cause uneven anastomosis tension on both sides of the wound, tear the surface tissue of the wound and cause anastomosis failure, which will bring pain and even enlargement of the second wound suture to the patient Therefore, th...

Problems solved by technology

If there is a lack of staples in the finished stapler, it will cause uneven anastomosis tension on both sides of the wound, tear the surface tissue of the wound and cause anastomosis failure, which will bring pain and even enlargement of the second wound suture to the patient Pain, which increases the risk of surgical failure, so the finished stapler must ensure that the staples are embedded in the mold base without any defects, which requires strict quality inspection of the stapler during production

Because the staples are very small and densely embedded in the micro-narrow slots of the mold base, common optical imaging and machine vision technologies cannot detect the integrity of the staple embedding, and manual visual inspection is also difficult to observe and easily fatigued, resulting in omissions or judgment error

Although the current radiation transmission detection method can solve the visual imaging problem of staples, it has disadvantages such as expensive equipment, inconvenient maintenance, and inevitable radiation leakage that may cause injury to the detection operator.
