Description
Technical field
This utility model relates to a kind of perforator, particularly relates to a kind of dynamical percutaneous puncture device, for medical instruments field.
Background technology
In treatment clinical course, particularly in part endoscopic surgery, usually need percutaneous puncturing operation.Traditional puncture risks is larger.
Chinese patent 201410292005.6, discloses a kind of perforator, and it is mainly applicable in the laparoscopic surgery of human body.This utility model comprises thimble assembly, black box, the gentle valve component of needle assembly, it is characterized in that: in thimble assembly, Compress Spring, support bar and alignment pin are also installed, Compress Spring and support bar contact with each other and are arranged between sleeve pipe lower cover and sleeve pipe upper cover, alignment pin and sleeve pipe top cap integral and make to pass through interference fit between sleeve pipe upper cover and sleeve pipe lower cover; Sleeve pipe covers and has elongated slot, bayonet slot, locating slot, spring eye and support bar locating hole; The lower end of sealing lower cover is also provided with and the rotary buckle sealing lower cover and be connected, and this rotary buckle is matched with described locating slot by bayonet slot and elongated slot.This structure relative complex, and complicated operation, bring some inconvenience to operation.
Utility model content
This utility model mainly solves the deficiencies in the prior art, a kind of compact conformation is provided, for different patient, the puncture sheath pipe of different length, external diameter specification can be selected, even same patient, also according to the needs for the treatment of, the puncture sheath pipe of various outer diameter, length specification can be used instead in art, and the dynamical percutaneous puncture device of one that perforator main body can connect with the puncture sheath pipe of aforementioned arbitrary specification.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of dynamical percutaneous puncture device, comprise puncture sheath pipe and main body, the top of described puncture sheath pipe is provided with outer pipe seat, the bottom of described main body is provided with main body joint, described outer pipe seat and main body joint fix adjustment by locknut, the top of described main body is provided with straight pipe, the top of described straight pipe is provided with the sealing cap matched with straight pipe, the lateral wall of described main body is provided with the lateral drainage pipe be connected with main body, longitudinal perforate is provided with in described lateral drainage pipe, described lateral drainage pipe overcoat has adjusting ring, the outer wall of described puncture sheath pipe is provided with scale.
As preferably, the bottom of described main body joint stretches in outer pipe seat, and described main body joint is locked by hold-down nut mutually with locknut.
Puncture sheath pipe is the inserting paragraph that effectively punctures, and have different lengths, external diameter optional, its outer wall indicates scale.The obturator (as shown in Figure 2) that puncture sheath pipe coupling is corresponding, the mid-guide wire passage of this obturator.Perforator main body is made up of straight pipe and lateral drainage pipe, can connect with the puncture sheath pipe of aforementioned arbitrary specification.Straight pipe socket sealing cap, can insert adaptive endoscope.Lateral drainage pipe one end is connected to straight pipe sidewall, and through with straight pipe; The other end can connect drainage tube automatic jet, also can connect receiving flask, vacuum extractor, thus improves attraction efficiency.The longitudinal perforate of lateral drainage Guan Youyi, separately has an adjusting ring.Longitudinal perforate and adjusting ring can be used alone, also can conjunctive use, for regulating the size of negative-pressure sucking.
Described puncture sheath pipe is the inserting paragraph that effectively punctures, and has different lengths, external diameter specification optional.Its length is 110mm, 145mm, and its external diameter is Fr12, Fr14, Fr16, Fr18.And have corresponding obturator to match.For different patient, the puncture sheath pipe be applicable to can be selected, even same patient, also according to the needs for the treatment of, in art, use the puncture sheath pipe of different length, external diameter specification instead, and perforator main body can connect with the puncture sheath pipe of whole specification.
If clinical needs, by this utility model and endoscope's use in conjunction, the definition in the scope visual field can be promoted, reduce injection pressure, shorten operating time, improve procedure efficiency, reduce operation risk, reduce apparatus loss, carry out the mode of operation of limit treatment, the controlled attraction in limit efficiently, contribute to the characteristic operative treatment project starting Microendoscopic.
Operation principle: in aforementioned endoscopic surgery, during concrete enforcement this utility model, first selects the puncture sheath pipe of appropriate length, external diameter, inserts corresponding obturator (as shown in Figure 2), screw the puncturing kit that composition is for subsequent use.Under B ultrasonic or movable C-shaped arm X-ray machine orientation direction, 18G puncture needle accurately penetrates target location, exits nook closing member, inserts guide wire, exits puncture stylophore pipe.Guide wire penetrates puncturing kit for subsequent use, under guide wire guiding, according to the scale of puncture sheath pipe outer wall, safely, penetrates target location exactly.Exit obturator, perforator main body is docked with puncture sheath pipe and screws.Described lateral drainage pipe one end connects receiving flask, vacuum extractor, debugging adjusting ring, and longitudinal perforate, the size of test, adjustment suction pressure.
After completing above-mentioned steps, endoscope is inserted this utility model through the sealing cap of straight pipe port, opens endoscope's water intaking valve, open adjusting ring, or longitudinal perforate, enter mirror to target location, carry out observing or symptomatic treatment.Need depending on operation, the closed adjusting ring of part, or longitudinal perforate, can obtain less negative pressure suction force, for adsorbing less tissue debris and the perfusion fluid of muddiness, promoting the definition of surgical field of view, alleviating injection pressure.Also optionally adjusting ring can be closed completely, or longitudinal perforate, larger negative pressure suction force can be obtained, for adsorbing larger tissue debris and the perfusion fluid of muddiness.Now can promote the definition in the scope visual field further, reduce injection pressure, shorten operating time, improve procedure efficiency, reduce operation risk, reduce apparatus loss, carry out the mode of operation of limit treatment, the controlled attraction in limit efficiently, contribute to the characteristic operative treatment project starting Microendoscopic.
The dynamical percutaneous puncture device of the one that this utility model provides, compact conformation degree is high, the definition in the scope visual field can be promoted, reduce injection pressure, shorten operating time, improve procedure efficiency, reduce operation risk, reduce apparatus loss, carry out the mode of operation of limit treatment, the controlled attraction in limit efficiently, contribute to the characteristic operative treatment project starting Microendoscopic.
