The invention provides a collision test device and relates to a test device. The collision test device aims at solving the problems that an existing collision test device is complex in structure, capable of conducting emission only through matching between a balancing body and a collision body, low in gunpowder utilization rate and serious in pollution to a test field. According to the collision test device, a working table is horizontally arranged and fixedly connected to a foundation; a first base, a second base and a third base are sequentially and fixedly connected to the working table; a first braking unit is mounted on the first base; a second braking unit is mounted on the second base; a counter-recoil unit is mounted on the third base; a transmitting tube body penetrates through the first braking unit, a first transmitting tube through hole, the second braking unit, a second transmitting tube through hole, the counter-recoil unit and a third transmitting tube through hole in sequence, and the transmitting tube body, the first transmitting tube through hole, the second transmitting tube through hole and the third transmitting tube through hole are arranged in a spaced mode. The collision test device is scientific and reasonable in structural design and low in manufacturing cost and is applied to high-speed large-mass collision physical tests, and the transmitting track of the collision body is accurate.

The invention discloses a minimally invasive positioning tool for a laparoscopic surgery and a protected supporting and positioning method of the tool, and relates to a minimally invasive positioning tool and a minimally invasive surgery method. A pneumoperitoneum operation mode of an existing laparoscopic surgery is very harmful to human bodies and large in wound, surgical difficulty and dangerousness are increased, other pneumoperitoneum modes are very harmful to patients and cause many complications, and standard operation is difficultly realized as an affected part of an abdominal cavity needs to be cut by the aid of experience of a doctor due to a narrow surgical field. A unilateral slide can be connected with a detachable base, a movable base is in sliding fit with the unilateral slide, a supporting component is arranged on the movable base, a buffer type guide head is arranged at one end of an intubation tube, a gas filled bag is arranged inside the intubation tube and communicated with a gas source, and a plurality of slot holes are formed in the intubation tube. The protected supporting and positioning method is characterized in that the gas source is started, gas flow with a gas pressure value P is led into the gas filled bag of the intubation tube, and the gas filled bag is filled with gas to form multi-point supporting or arc-shaped supporting. The minimally invasive positioning tool and the protected supporting and positioning method are used for the laparoscopic surgery.
