Description

This utility model belongs to the field of medical devices and refers to a separate guide clamp for minimally invasive surgery of the anterior mediastinum.

Technical background

Because surgery is performed within the anterior mediastinum and outside the sternum of the sternum, the surgery of tumor resection of the posterior mediastinum from the xiphoidal sternum using the new endoscope currently requires a special tool to accomplish the purpose of movement from the incision of the bilateral interproximal ribs to reach the incision of the xiphoid process, and also to avoid the injury of the bilateral pleura as well as the right pleura. Due to its own structure and peculiarity of anatomy from the curved site of the pleura, normal separate clamp has the following fatal flaws, so it is not applied to this new type of minimally invasive surgery of the anterior mediastinum: first, the clamp head is too sharp, which Breast-paw fracture, as well as adverse effects on surgery, can cause problems such as atelectasis of the lungs and the gas screw after the pleura is broken, worst may be life-threatening. Second, normal separate clamp is too short, which can not satisfy the requirement of surgery. Third, the existing separate clamp is made of hard material, linear separate clamp can not be bent, while the angle of the bent clamp is for the separation of ribs and sternum, therefore, the surgery can lead to pleura.

Content of the invention

The utility model refers to a separate guide clip for minimally invasive surgery of the anterior mediastinum to release the brachial fracture caused by the existing separate guide clamps.

The technical solution of the utility model separate guide clamp for minimally invasive surgery of the anterior mediastinum, including the clamp-like body made of stainless steel, in front of the body there are two clamping arms, the end points of the clamping arms are dull and bend to one side of the platform in which the Body is located near the free end point of each clamping arm arcuate opening is arranged, when the two clamping arms are closed, a closed hollow body is formed, and there are two handles at the rear end of the body, on the inner sides of the handles are provided according to notches To connect the two handles, on the adjacent surfaces of the detents are sawtooth-like interventions.

• 1. die Gesamtstruktur ist einfach und steht in Übereinstimmung mit den Anforderungen der zwischenmenschlichen Rippenform und -struktur, der stumpfe Kopf des vorderen Spannarms und die gebogene Struktur können die Gewebe sanft schieben und trennen, gleichzeitig können sie die Verletzung des Brustfells durch die scharfe Klemme vermeiden;
• 2. die Trennungseffizienz ist zuverlässig, beim Schließen der beiden Handgriffe können beide Rasten zusammenbeißen, was es sicherstellt, dass zwei Spannarme während der Chirurgie nicht geöffnet werden können, damit wird die Verletzung der Gewebe vermieden und die Sicherheit der Chirurgie garantiert. Wenn es beim Trennen des Gewebes nötig ist, ist es einfach, die Rasten voneinander zu trennen.
• 3. der glatte Kreis am vorderen Ende der stumpfen bogenförmigen Klemme kann auch als Führungsloch des fixierten Riemens des Brustbeins benutzt werden, es ist einfach zu bedienen und kann die Zeit der Chirurgie sowie der Anästhesie sparen, gleichzeitig kann auch der Schaden des Missbrauchs vermieden werden.

The peculiarities of the utility model lie in the fact that on the surface of the two clamping arms sawtooth-like structure is designed. When closing the two arcuate openings a smooth circle with a diameter of 1.5 cm is formed. The degree of the angle α between the bending portion of the front clamp arm and the horizontal direction is 30 ° to 50 °. The positive effects of the utility model are,

• 1. The overall structure is simple and in line with the requirements of the interpersonal rib shape and structure, the blunt head of the front tensioning arm and the curved structure can gently push and separate the tissues, while avoiding the injury of the pleura by the sharp clamp ;
• 2. the separation efficiency is reliable, closing both handles can clench both latches, ensuring that two clamping arms can not be opened during surgery, thus avoiding tissue injury and guaranteeing the safety of surgery. When it is necessary to separate the tissue, it is easy to separate the detents.
• 3. The smooth circle at the front end of the blunt arcuate clamp can also be used as a guide hole of the fixed strap of the sternum, it is easy to use and can save time of surgery as well as anesthesia while also avoiding the damage of abuse.

Concrete implementation process

In the following a detailed representation of the utility model with the help of illustrations and concrete implementation procedure is given. This utility model provides a separate guide clamp for minimally invasive anterior mediastinal surgery, including a clamp body 1 made of stainless steel, at the front end of the body 1 stand two clamping arms 2 , the free points of the two clamping arms 2 are dull, and the free end point of the two clamping arms 2 bends to one side of the platform on which the body is 1 located. The arcuate clamping arms may pass along the edge of the sternum and ribs into the body of the patient by allowing the pleura to be pushed and separated from the connective tissue; the blunt head of the tensioning arms can efficiently avoid the possibility of sharp-peen injury so surgery can be performed without damage to the sternum and ribs to avoid adverse effects of the pleura fracture on the surgical procedure.

Near the free end point of each tension arm 2 become arcuate openings 3 erected when the two clamping arms 2 closed, the arcuate openings 3 form a closed hollow body whose diameter is a smooth circle with a diameter of 1.5 cm, then at the other place of the clamping arms 2 sawtooth-like structure is designed on both surfaces (see ), the degree of the angle α between the front part of the tensioning arm 2 and the horizontal direction is 30 ° to 50 °, the optimum angle α is 40 °, this angle ensures that the arcuate clamping arms 2 along the edge of the sternum and ribs into the body of the patient.

The back end of the body 1 has two handles 5 , on the inner side of the handles 5 be according to rest 4 designed on the adjacent surface of the notches, it is provided with a sawtooth-like structure.

In the application you close the two handles 5 The snaps on it can clench what it ensures that two clamping arms 2 During the surgery can not be opened, so that the injury of the tissues is avoided and the safety of the surgery is guaranteed. If it is necessary to separate the fabric, it is easy to use the catches 4 separate from each other and the clamping arms 2 then, the tissue separation is performed efficiently, speeding up the process of surgery and reducing the risk of surgery.

The utility model has been made of stainless steel with suitable hardness, then the deformation of the device will never come, and the separate efficiency of the separation is to be considered exactly; the utility model can be designed in different sizes according to the actual situation in order to adapt to different conditions of the patient, thus ensuring the effect of the use.
