Laparoscopic instruments and trocars are provided for performing laparoscopic procedures entirely through the umbilicus. A generally C-shaped trocar provides increased work space between the hands of the surgeon as well as S-shaped laparoscopic instruments placed through the trocar when laparoscopic instrument-trocar units are placed through the umbilicus. In order to facilitate retraction of intra-abdominal structures during a laparoscopic procedure, an angulated needle and thread with either one-or two sharp ends is provided. Alternatively, an inflatable unit having at least one generally C-shaped trocar incorporated within the unit's walls can be placed through the umbilicus following a single incision. Generally S-shaped laparoscopic instruments may be placed through the generally C-shaped trocars to facilitate access to intra-abdominal structures.

A surgical training system includes a tracking system for tracking the position of one or more instruments during a training procedure and objectively evaluating trainee performance based upon one or more metrics using the instrument position information. Instrument position information for the training procedure can be compared against instrument position information for an expert group to generate standardized scores. Various training object can provide realistic haptic feedback during the training procedures.

An implantable prosthesis for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion of a laparoscopic procedure. The prosthesis includes a patch and/or plug having a body portion that is larger than a portion of the opening or weakness so that placement of the body portion against the defect will cover or extend across that portion of the opening or weakness. At least one tether, such as a strap, extends from the patch or plug and may be manipulated by a surgeon to position the patch or plug relative to the repair site and/or to secure the patch or plug relative to the opening or weakness in the tissue or muscle wall. The tether may be configured to extend through the defect and outside a patient's body to allow a surgeon to position and/or manipulate the patch from a location outside the body. An indicator may be provided on the tether as an aid for a surgeon in determining when the patch or plug has been inserted a sufficient distance within the patient. A support member may be arranged in or on the patch or plug to help deploy the patch or plug at the surgical site and/or help inhibit collapse or buckling of the patch or plug. The patch or plug may be configured with a pocket or cavity to facilitate the deployment and/or positioning of the patch or plug over the opening or weakness.

A surgical simulation system is provided. The system includes at least one simulated body organ placed upon the base of an organ tray and at least one covering layer placed over the simulated body organ. At least one of the simulated body organ and covering layer includes electro-conductive gel that is operably severable under application of electrical current to simulate electrosurgery in a training environment. The training environment comprises a top cover connected to and spaced apart from a base to define an internal cavity that is partially obstructed from direct observation by a practitioner. The tray, simulated body organs and covering layer are placed inside the internal cavity for the practice of laparoscopic surgical procedures.

The invention discloses a puncture sheath with suturing function, which is characterized in that it comprises a sheath body and a peritoneal stapler inserted into the sheath body. The rod-shaped stapler body of the peritoneal stapler is inserted into the laparoscopic surgical wound through the puncture sheath, and the suture needle on the stapler body or the head flap passes through the peritoneum, and the suture thread ends are left on the head flap or the stapler body, and then pulled out When the suturing device body is out, the thread end is brought out to realize the suturing of the wound. The stretched head flap can position the abdominal wall tissue, prevent leaks, and avoid suture damage to other organs and tissues. The invention has simple operation and good suturing effect, can effectively prevent secondary damage during wound suturing, and reduce the incidence of incisional hernia.

The invention relates to a collaborative awareness laparoscopic surgery constant-pressure support system and an implementation method thereof, on the basis of an ultrasonic knife with an attraction function, real-time pressure of an abdominal cavity is automatically aware, the size of an air inlet valve is dynamically adjusted according to a standard set value, dynamic air supply is realized, andabdominal cavity pressure balance in the surgery process is achieved; a historical database is used for calculating and recording the optimal air pressure of patients with different disease types (stomach cancer and colorectal cancer), disease periods, genders, ages, body conditions and weights (BMI) in the actual operation process, the air pressure actually needed by the operation is accurately set, the system has a guiding significance more generally, and doctors with less operation experience are helped to set the reasonable abdominal cavity air pressure; a big data clustering analysis technology is applied to continuously optimize the data, so that a better effect is achieved; influence on the existing operation system is small, and the compatibility and the usability are high; the laparoscopic surgery efficiency and effect can be improved, the pain and postoperative complications of the patient are reduced, and the operation burden of the doctor is relieved.

The invention relates to the field of medical equipment, in particular to a biological tissue specimen taking-out device for laparoscopic surgery. The device comprises a laparoscopic cannula and a ventilation pipeline, the ventilation pipeline is used for picking up a biological tissue specimen cut off by operating forceps on the laparoscopic cannula, and a hoop sleeve is arranged on the outer side wall of one end of the ventilation pipeline. A barb mechanism used for preventing biological tissue from falling off is arranged on the inner wall of the end, close to the hoop sleeve, of the ventilation pipeline, a suction mechanism used for absorbing blood is arranged on the side wall of the end, close to the hoop sleeve, of the ventilation pipeline, and the suction mechanism is in transmission connection with the barb mechanism. According to the biological tissue sample taking-out device for the laparoscopic surgery, large-size biological tissue can be taken out conveniently, the biological tissue is prevented from falling off from the ventilation pipeline, the situation that the falling biological tissue possibly contains tumor cells, and consequently implantation and metastasis of tumors are caused is prevented, the reliability of taking out the biological tissue is improved, and the integrity of the specimen can be kept as much as possible in the specimen taking process.

The stapler of the invention is a surgical stapler/cutter that allows latero-lateral intestinal anastomosis, for both open surgery and laparoscopic surgery, at a distance from the openings used to insert the instrument. The stapler is based on the conventional structure of this type of stapler, and one of the fundamental features thereof is that an interspace (12) that determines a space for inserting the free ends (13, 13′) of the tissues (8, 8′) to be joined, is determined between an articulation shaft (3) of the two jaws (4, 5) of the stapler and the front end at which are disposed forms (6) and vertically movable teeth (9) on which staples (7) are disposed. This prevents the staples for the anastomosis and those for the removal of the pathological area from crossing when the area to be removed is cut. The invention also provides for the inclusion, in the described inter-space (12), of an Infrared Data Association (IrDA) device for testing blood flow that transmits a signal to a luminous signalling device which is visible to the user and which allows the degree of tissue vascularisation to be assessed.
