Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical auxiliary device technology, specifically relating to an intraoperative human tissue traction passage bag and its usage method. Background Technology
[0002] Surgical procedures are medical processes that treat diseases, injuries, or deformities using instruments, techniques, or manipulations. In surgical procedures, traction of tissues or organs is often necessary to retrieve resected tissue specimens or to reposition tissues to appropriate anatomical locations. For example, in a three-incision esophagectomy, the cancerous lesion needs to be removed, resulting in an esophageal defect. To ensure normal esophageal function, a portion of the stomach tissue needs to be reshaped into a "tubular stomach," which is then pulled from the abdomen to the chest or neck and anastomosed to the esophagus. Currently, due to the lack of specialized traction devices, surgeons often use sterile cotton ropes, urinary catheters, or gastric tubes for traction. However, because of the presence of organs in the chest and abdomen, the diaphragm, and the fact that minimally invasive surgeries are performed endoscopically with small surgical eyes and narrow surgical fields, incorrect traction direction can often encounter obstacles, causing traction blockage, affecting the procedure, and even leading to rope breakage or tissue damage. Summary of the Invention
[0003] The purpose of this invention is to address the problems in existing surgical techniques where the lack of suitable pathways for traction of intrathoracic and abdominal tissues leads to obstruction, failure, and even damage to the patient. This invention proposes an intraoperative tissue traction pathway bag and its usage method. The device of this invention can establish a traction pathway at the target surgical location within the human body, ensuring a smooth traction path for the tissues, reducing traction obstruction, improving the success rate of tissue traction, and protecting the body from injury.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An intraoperative human tissue traction access bag includes an access bag body and a medical sterile packaging bag; the access bag body is placed inside the medical sterile packaging bag; the access bag body is elongated; a set of suture fixation areas are connected to each end of the access bag body; a rubber head is connected to the front of each set of suture fixation areas; and a traction rope is provided inside the access bag body.
[0005] The access bag can create a traction pathway for human tissue within the patient, reducing obstruction during the traction process. The length of the access bag is between 20 and 50 cm, and at least three different length specifications can be provided. The sterile medical packaging bag is used to hold the disposable access bag, which can be torn or cut open for use. The suture fixation area is used for clamping with surgical forceps or temporarily sewed onto the patient's body tissue for fixation. The rubber head is used by medical staff to clamp and insert it into the appropriate surgical position within the patient's body. The traction rope is connected and fixed to the human tissue to be traction using suture fixation or other methods. Pulling the other end of the traction rope can pull the human tissue to be traction to the predetermined position for the corresponding surgical operation.
[0006] As a further technical improvement, an insertion auxiliary pocket is provided between the suture fixation area and the rubber head. The insertion auxiliary pocket is made of the same rubber material as the rubber head and is connected to the rubber head; the insertion auxiliary pocket is a small pouch, through which a slender medical instrument can be inserted to help push the access bag into the corresponding surgical site on the human body.
[0007] As a further technical improvement, the rubber head is provided with a traction hole. The traction hole allows the user to clamp and pull the rubber head using medical instruments such as surgical forceps.
[0008] As a further technical improvement, the access bag is made of soft, thin rubber; a width-limiting mesh is installed on the inner wall of the access bag, ensuring that the maximum width of the access bag after it is expanded is less than 6 cm. This width-limiting mesh restricts the maximum expansion width of the access bag. During surgery, some medical instruments, such as surgical forceps, are inserted through the access bag depending on the situation. If the bag is expanded too much inside, it could damage the patient's internal organs and tissues. By limiting the maximum expansion width of the access bag, the surgical instruments cannot be further expanded, thus protecting the internal organs and tissues.
[0009] As a further technical improvement, the thickness of the stitched fixing area is greater than the thickness of the passage bag body. This design allows for better stitching and fixation of the fixing area, making it less prone to damage.
[0010] As a further technical improvement, the medical sterile packaging bag contains a medical lubricant that wets the bag body. The medical lubricant can be medical paraffin oil, etc.
[0011] The above describes the method of using the intraoperative human tissue traction passage bag: Placement of the access bag: During the surgery, a non-natural cavity is created inside the body using minimally invasive surgical techniques; the surgeon opens the sterile medical packaging bag and removes the access bag; one end of the rubber head is held with surgical forceps, or a thin instrument is passed through a set of traction holes, or a medical instrument is inserted into the auxiliary bag; the access bag is pushed into the artificially created non-natural cavity or a natural anatomical cavity that already exists in the body, and the access bag passes through the organ tissue layer until it reaches the predetermined surgical position; the other end of the access bag is then moved to another predetermined surgical position. Establishing a traction pathway: Cut open the suture fixation area at both ends of the pathway bag with surgical scissors to expose the two ends of the traction rope; suture the suture fixation area to the patient's tissue, or clamp it with surgical forceps; at this time, the two ends of the pathway bag are located at two predetermined surgical positions in the human body, establishing a traction pathway for human tissue to pass through these two surgical positions. Tissue traction: The tissue to be traction is fixed to one end of a traction rope using sutures or other methods. The surgeon pulls the other end of the traction rope, drawing the tissue into the traction pathway established by the access bag. As the traction rope is pulled out, the tissue is brought to the new, predetermined surgical target position, where it can then be sutured to the new target or removed. Finally, the access bag is removed. During the traction process, surgical forceps or other instruments can be used to hold and fix the access bag in place to prevent slippage.
[0012] The technical solution of this invention has the following beneficial effects: 1. The device of the present invention can establish a traction channel in the thoracic and abdominal cavities of the human body through the channel bag, and pull the human tissue during surgery along the established channel by the traction rope. This reduces the jamming of human tissue during the traction process, avoids problems such as traction failure due to the breakage of the traction rope caused by jamming, optimizes the surgical operation steps, reduces surgical risks, and is of great significance to ensuring surgical safety.
[0013] 2. The device of the present invention, through the rubber head and the insertion auxiliary bag, allows doctors to use surgical instruments to clamp or push the access bag into the corresponding predetermined surgical position in the patient's body, making the operation more convenient and effective and reducing the difficulty of operation.
[0014] 3. The group suture fixation area of the device of the present invention can be fixed to the patient's tissue by clamping or suturing, so that the established traction channel can maintain its current position, which is conducive to subsequent traction operations on human tissue.
[0015] 4. The device of the present invention has a width-limiting mesh on the inner wall of the passage bag, which can limit the opening size of medical devices inserted into the passage bag, avoid the medical devices opening too large and causing damage to the patient's organs and tissues, and further protect the safety of the operation.
