Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of tissue suspension for operation, in particular to a disposable tissue suspension device.
[ background of the invention ]
During minimally invasive surgery, the surgical field is often affected by body tissues such as organs, muscles, cartilage, and the like. The traditional approach is to move the patient to change the patient's posture (e.g., Trendelenburg position) to obtain a better surgical field. This method is inconvenient for the physician and may also cause greater trauma to the patient.
Therefore, in order to obtain a better surgical field during the operation and to increase the safety of the operation, instruments for retracting, separating and fixing tissues and organs have been developed. Chinese patent document CN201120103023 provides a three-leaf fan-shaped forceps, which comprises a main body, and the main body is in a forceps shape. The head of the main body is provided with two spreading clamp leaves and one fixed clamp leaf, and the bottom ends of the three clamp leaves are provided with a sliding groove. The bottom ends of the three blades are overlapped and connected with a pull rod connecting pin. The pull rod connecting pin is connected with the movable handle through the pull rod, and when the pliers are used, the handles are buckled down, so that the pliers pages can be unfolded in a fan shape. Then the sector forceps can be used for moving the organ to optimize the surgical field. The instrument is originally designed for the direct-view operation of human bodies, and is improved for the use of minimally invasive surgery in the practical application. Indeed, the use of the present instrument allows the tissues or organs to be plucked to expose the surgical field, but the instrument still suffers from several important drawbacks. In minimally invasive surgery, the fewer the number of minimally invasive orifices, the better in order to reduce patient pain. When using the instrument, forceps need to be applied through the minimally invasive aperture. If the tissue or organ is to be moved and still held, the instrument is left in the body, which occupies a minimally invasive aperture. Also, in this case, the surgery would require an additional assistant to operate and secure the instrument. Therefore, the use of the instrument to retract and secure body tissues and organs in minimally invasive surgery is clearly not the most desirable solution.
Chinese patent document CN101933822A provides "tri-bladed forceps with channel for minimally invasive surgery" which changes the linear type of forceps rod into a zigzag shape and has a channel in the middle of the forceps rod to allow other instruments to pass through. The fold line-shaped clamp rod forms a certain angle with the channel on the clamp rod after entering the abdominal cavity, thereby creating an operation space for the channel entering the instrument. However, this does not completely solve the above-mentioned technical drawbacks, and the position of the instrument still needs to be manually maintained during the operation. Moreover, the guide wire for controlling the relaxation of the forceps leaves and the bending of the forceps rod can pass through the same minimally invasive aperture, which inevitably reduces the aperture size of the instrument channel. Moreover, these devices are made of non-disposable materials, which control the porosity of the mechanical structure of the forceps, easily leaving the patient's body fluids and tissues in the pores, requiring careful cleaning and sterilization after the operation.
At present, minimally invasive surgery advocates reducing the number of minimally invasive channels to reduce postoperative pain of patients, and like single-pore minimally invasive surgery, the minimally invasive surgery can greatly reduce postoperative pain of patients. Therefore, the research on instruments which can not occupy minimally invasive pore canals and can effectively retract and fix human tissues or organs to expose the surgical field is significant.
The company applies for a novel tissue suspender in 2019, and the novel tissue suspender is disclosed as 201910268788.7, and although extra puncture is effectively avoided to manufacture holes, the load-bearing capacity of the suspender main body is low, and the requirement of tissue support cannot be met.
Therefore, there is a need to provide a new single use tissue hanger that solves the above problems.
