Number in the figure represents: 1-operate portions, 2-connecting rod, 3-depression, 4-handle, 5-locator card, 6-positioning button, 7-bull stick, 8-fixed pulley, 9-bracing wire, 10-spacing bucket, 11-fixing head;
Detailed description of the invention
For Minimally Invasive Surgery, the most important thing is under the prerequisite of Wicresoft, utilize limited space to complete operation, to alleviate sufferer misery, be beneficial to recovery; And to operations such as Thyreoidines, as excessive in its otch, larger cicatrix certainly will be left during healing, bring psychological burden to patient.Therefore, in operation process, apparatus with the use of extremely important, how accurately, promptly to operate under limited space, just further requirement proposed to operating theater instruments.
The operating theater instruments of this stripping proposed in this utility model and tractive thyroid gland leaf, as shown in the figure, the work of stripping, tractive gland leaf can be completed in operation simultaneously, and traditional apparatus is peeled off and tractive separates, this just needs more space to leave instrumentation for, need more doctor's auxiliary operation simultaneously, increase operating difficulty undoubtedly.
This operating theater instruments, comprise operate portions 1 and handle 4, described operate portions 1 is connected by connecting rod 2 with handle 4, the lateral cross section of operate portions 1 is arc-shaped, linkage is provided with in operate portions 1, linkage is connected internally to the positioning button 6 be arranged on handle 4 by connecting rod 2 by bracing wire 9, modulation position button 6 can change the angle between operate portions 1 and handle 4.
Operate portions 1 and handle 4 form T-shaped structure after utilizing connecting rod 2 to be connected, and not only convenient operation doctor grips, and is more prone to exert all one's strength, and contributes to long operation technique.Operate portions 1 lateral cross section is arc, i.e. tiles structure, and this structure can utilize its marginal portion to peel off thyroid gland leaf carefully, and can with its cave in 3 position gland leaf held and supports, play traction action.
Be subject to the restriction of operation opening position and operating doctor operation, for the operation doctor of auxiliary pulling thyroid gland leaf, the space left and position are abundant not, so for operating theater instruments, just require that it can coordinate doctor to operate as far as possible easily.In this programme, consider the practical problem run in operation process, be provided with the structure of adjustable angle between operate portions 1 and connecting rod 2, namely for operation doctor, regardless of its position, all by the angle between adjustment operate portions 1 and handle 4, carry out effective tractive to gland leaf, this has just left sufficient space to the position of operation doctor.
Consider the actual environment of operation, positioner can not be very complicated, and apparatus outer surface is more simple better, therefore for the adjustment of angle, can conveniently be realized by the positioning button 6 on handle 4.Positioning button 6 controls linkage by bracing wire 9, and when rotating positioning button 6 and making bracing wire 9 tighten up, linkage drives operate portions 1 to move towards near the direction of connecting rod 2, just changes the angle between operate portions 1 and connecting rod 2.
This utility model proposes following prioritization scheme further:
The central angle of lateral cross section is 150 ° ~ 180 °.
Because the lateral cross section of operate portions 1 is arc-shaped, and circular arc correspond to certain central angle.For operate portions 1, the shape of its depression 3 should limit within the specific limits, too small then can not tractive gland leaf effectively, excessive then bad stripping.Consider, in conjunction with inventor's practical application, the central angle that circular arc is corresponding should be advisable with 150 ° ~ 180 °, and namely the both sides of the edge of operate portions tilt slightly, and edge is sharp and not sharp; Sharp and not sharply refer to that edge is the disc of convergent, not sharply, but be convenient to carry out strip operation; And operate portions smooth surface, be beneficial to protection surrounding tissue, clamp can be replaced to play scratch pulling out, stop, pushing effect.
The width of operate portions 1 is no more than 2cm, and the width of operate portions 1 refers to the chord length of the circular arc cross-sections of operate portions 1 correspondence.This width is beneficial to the operations of operate portions 1, as stopped trachea, neuroprotective and blood vessel etc.
Linkage comprises the fixed pulley 8 be fixedly installed in operate portions 1 sidewall, described bracing wire 9 one end is fixed in operate portions 1 inwall, then the spacing bucket 10 walked around fixed pulley 8 and arrange in the sidewall, positioning button 6 is connected internally to through connecting rod 2, the stiff end of bracing wire 9 in operate portions 1 sidewall is between fixed pulley 8 and spacing bucket 10, and fixed pulley 8 is near the front end of operate portions 1.
This linked manner herein proposed, its principle is, because bracing wire 9 is nonflexible lines, when at one end tightening up, it can not stretch, and utilizes this structure formed, and in the non-shrinking situation of bracing wire 9, bracing wire 9 can drive operate portions 1 to move to a direction.As shown in Figure 2, if carry out cutting vertically from the center of operate portions 1, the operate portions 1 so contacted with cutting plane during cutting is the sidewall of operate portions 1, and this nested structure is just arranged in the sidewall.Be fixed pulley 8 foremost, middle part is the stiff end of bracing wire 9, then after be spacing bucket 10, and bracing wire 9 stiff end and fixed pulley 8 are preferably arranged in the position of operate portions 1 front end 1/3rd.When adjusting angle, the other end of bracing wire 9 tightens up, and stiff end limits through the position of vicarious, the spacing bucket 10 of fixed pulley 8, so now fixed pulley 8 is subject to the power along bracing wire 9 direction, can be analyzed to and is parallel to connecting rod 2 direction and two component perpendicular to connecting rod 2 direction.Component perpendicular to connecting rod 2 direction is cancelled due to the restriction of connecting portion (rotating shaft), the power being parallel to connecting rod 2 direction then drives operate portions 1 front end to move towards near the direction of connecting rod 2, realizes with this function adjusting angle between operate portions 1 and connecting rod 2.
Be provided with bull stick 7 in handle 4, bull stick 7 one end passes handle 4 and is connected, on the movable fixing head 11 being arranged on handle 4 inside of the other end with positioning button 6; Positioning button 6 is connected with bracing wire 9 by bull stick 7, and bracing wire 9 end winding support is on bull stick 7.
For the adjustment process of handle 4 end, tighten up bracing wire 9 in this programme by a bull stick 7, when rotating positioning button 6, positioning button 6 drives bull stick 7 to rotate, and bull stick 7 rotates and bracing wire 9 is wrapped on bull stick 7, and realizes the contraction of this end bracing wire 9.
Bull stick 7 penetrates handle 4 from handle 4 side, can moving axially along handle 4; The bull stick 7 of handle 4 outside is symmetrically arranged with locator card 5, handle 4 side is provided with the stopper slot coordinated with locator card 5, when being promoted vertically by bull stick 7 to make locator card 5 be arranged in stopper slot, bull stick 7 can not rotate.
After adjusting position, a fixed form comparatively easily should be had.Be provided with locator card 5 and stopper slot structure in this programme, wherein stopper slot can arrange multipair, rounded distribution, and locator card 5 can be able to be fixed in each position.Time fixing, after only needing to tighten up bracing wire 9, make locator card 5 aim at stopper slot, promote bull stick 7; When needing again to adjust, extract locator card 5 and rotate positioning button 6, position is fixed after adjusting again.
In operating process, scratch its hetero-organization of health, this operate portions 1 edge is sharp and not sharp round edge, and edge reduces, and thickness is slightly less than the thickness of other parts, can play good stripping effect; And handle 4 is provided with the depression 3 being convenient to grip, just coincide when gripping with staff, be convenient to doctor hand-held, anti-skidding effect can be played simultaneously.
