Abstract
The utility model relates to the puncture tool in the medical field. The utility model is realized by the technical proposal that the puncture tool comprises a puncture tube; an expansion tube is arranged outside the puncture tube; an internal fixing structure is arranged between the expansion tube and the puncture tube. The utility model is simple in structure and convenient for operation and can be fixed at the incision of the patient, making up the disadvantages of the background technology.
Description
Technical field
This utility model relates to the lancet device of medical field.
Background technology
Laparoscopic surgery is to guarantee that laparoscopic instrument enters the important channel of abdominal cavity operation in laparoscopically operation technique with lancet device.
Yet, existing laparoscopic surgery just stings in the abdominal cavity simply with lancet device, turnover along with laparoscopic instrument, this lancet device is subjected to the drive of laparoscopic instrument, can produce displacement, easily breaks away from patient's otch, cause the intravital carbon dioxide of patient to overflow, even the damage tissue, increase operating difficulty, even caused operative failure.
The utility model content
The purpose of this utility model provides a kind of laparoscopic surgery lancet device that can fix with patient's incision tissue, has remedied disadvantages of background technology.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of laparoscopic surgery lancet device, comprise puncture tube, and puncture tube is arranged with convergent divergent channel outward, is provided with the internal fixation structure between convergent divergent channel and the puncture tube.
As of the present utility model preferred, but described internal fixation structure comprises convergent divergent channel with puncture tube fixes and with the sealing ring that seals between convergent divergent channel and the puncture tube and run through also indentation or stretch out the spring of convergent divergent channel of sealing ring.
Sealing ring lock ring puncture tube and spring are to realize the sealing between sealing ring and puncture tube and the spring.But spring indentation or stretch out convergent divergent channel under the push-and-pull of manpower.
As of the present utility model preferred, described internal fixation structure also comprises the pipe of swelling between convergent divergent channel and puncture tube, and pipe box is on spring.
The expanding-contracting action that is set to spring of pipe provides a straight passage.
As of the present utility model preferred, described spring head-bent, spring head end point to the convergent divergent channel outside.
When the spring head was arranged in pipe, the swelling of spring head was in inside pipe wall; Because the spring head end points to the convergent divergent channel outside, therefore, when the spring head stretched out convergent divergent channel, the tissue of spring head end and patient's incision interlocked.
As of the present utility model preferred, this kind lancet device also comprises the external fixation structure.
As of the present utility model preferred, described external fixation structure is a round knot that can be undone by a pull.
After puncture tube and convergent divergent channel penetrate otch, with round knot that can be undone by a pull lock ring in convergent divergent channel and otch joint.
As of the present utility model preferred, described round knot that can be undone by a pull is made up of the arcuation fastener that arcuation hook spare reaches and arcuation hook spare is hinged.
As of the present utility model preferred, described arcuation hook spare one end is provided with hook, and described arcuation fastener one end is provided with the profile that matches with hook.
In sum, the utlity model has following beneficial effect:
When 1, this utility model being penetrated patient's otch, the spring head is arranged in pipe; Because the spring head-bent, spring is when being arranged in pipe, and the spring swelling is in inside pipe wall; After this utility model penetrates patient's otch, touch spring and pass the sealing ring part, make the spring head stretch out convergent divergent channel, after the spring head stretches out convergent divergent channel, the spring head end can fasten tissue, when laparoscopic instrument turnover puncture tube, because the drag effect between spring head end and the tissue makes this utility model be difficult to produce displacement;
2, the setting of external fixation structure is in order better this utility model to be fixed in patient's incision;
3, this utility model is simple in structure, and is easy and simple to handle.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this description, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
A kind of laparoscopic surgery lancet device shown in Fig. 1 to 5, comprises puncture tube 1, is arranged with convergent divergent channel 2 outside the puncture tube 1, and the diameter of convergent divergent channel 2 is provided with the internal fixation structure greater than the diameter of puncture tube 1 between convergent divergent channel 2 and the puncture tube 1.
But the internal fixation structure comprise with convergent divergent channel 2 and puncture tube 1 fixes and with the sealing ring 31 of sealing between convergent divergent channel 2 and the puncture tube 1, run through sealing ring 31 and indentation or stretch out convergent divergent channel 2 spring 32, be placed on the spring 32 and the pipe 33 of swelling between convergent divergent channel 2 and puncture tube 1.
Have finedraw on the sealing ring 31, be used to wear spring 32; This finedraw does not show in the drawings.
Connect by handle 321 between two spring 32 tail ends.
For better lancet device being fixed in patient's incision, present embodiment also comprises the external fixation structure.
The external fixation structure is a round knot that can be undone by a pull 4.
Round knot that can be undone by a pull 4 is formed by arcuation hook spare 41 and with the hinged arcuation fastener 42 of arcuation hook spare 41.
Arcuation hook spare 41 1 ends are provided with hook 411, and described arcuation fastener 42 1 ends are provided with the profile 421 that matches with hook 411.
After puncture tube 1 and convergent divergent channel 2 penetrate otch, by being connected round knot that can be undone by a pull 4 lock rings of hook 411 and profile 421 in convergent divergent channel 2 and patient's otch joint.
